She's making him look like an absent parent, and he's not. 

Not all parents are guardians, and not all guardians are parents. Every family is different, and it's best practice for schools not to assume that all their students have a mom and a dad who are caring for them at home. There's a reason teachers tell their students to bring permission slips home to "their parent or guardian" rather than just their parent. 

Some teachers want to be even more inclusive, telling kids to give permissions slips to "their grown-up." That could be a little too vague, because who exactly is their "grown-up"? A grandparent could be heavily involved in their grandchild's life without serving as a guardian. They shouldn't give their permission slip to just any grown-up who happens to be in their lives. The role of a guardian is much greater than that of an aunt who occasionally picks them up from school when their mom is busy. She probably shouldn't be the one who signs the test when they fail! She is an important, valuable member of the family, but she is not a guardian. It's essential that she not make decisions that guardians should make, and that she not identify herself as a guardian to her nieces' or nephews' schools. The school needs to know the identities of the adults caring for the children they educate for safety reasons.

  • Even just calling yourself a child's guardian when you're not can be incredibly insulting to the child's actual guardian. A grandmother boldly told her an employee at her son's school that she was the real guardian, despite his parents standing right next to her. When her son-in-law corrected her, all heck broke loose. 

  • Am I the bad guy for telling my mother in law she is not allowed to call herself my kid’s “guardian” again?

    I'm 36M, married to my wife (35F) for 6 years. We have one kid (6). My wife's mom has always been intense, like the kind of person who speaks in certainties and rewrites history in real time.

  • We've had a rocky relationship with her for years, but we've kept it polite because my wife still wants our kid to know his grandma.
    via u/HushedCanteen
  • The problem is she doesn't stay in the “grandma lane”. She oversteps in sneaky ways that sound helpful if you weren't there.
    via u/HushedCanteen
  • For example she'll tell my son "if you ever need a REAL grown up, you call me" while looking directly at me, or she'll say stuff like "I'm the only one who remembers your allergies" even though our kid doesn't have allergies.
    via u/HushedCanteen
  • She also loves to make little announcements to other people. Last year at a school thing she introduced herself to a parent as "basically his second mum" and my son looked confused and did that little kid laugh like, what?
    via u/HushedCanteen
  • I let it go, because my wife asked me to, and I told myself it was harmless ego.

  • This week was my son's school open house. It's not a holiday or anything, just the evening where kids show their classroom and the teacher does a quick chat.

  • My wife invited her mom because she said it would mean a lot to our son.
    via u/HushedCanteen
  • Fine. We get there, it's crowded, kids everywhere, and my son runs off to show his desk.
    via u/HushedCanteen
  • I'm standing with my wife, and her mom is doing her usual scanning-the-room thing. A staff member (not the teacher, more like the front office type) comes up and says, "Hi, are you his guardian?" and points at my son.
    via u/HushedCanteen
  • Before I even answer, my mother in law smiles and goes, "Yes, I'm his guardian. I handle all the important stuff for him." The staff member turns to me and my wife and goes, "Oh okay, great." My wife looks at me like please dont, but I felt my face get hot.

  • I said, calm but very clear, "No. You're his grandmother. I'm his dad and this is his mother." Her mom instantly does that wounded little laugh and says, "It's just a word, don't be so touchy." The staff member looked awkward and excused herself.
    via u/HushedCanteen
  • Then my mother in law starts hissing at me quietly, saying I embarrassed her, that I "undermined her role", that I always have to make everything about control.
    via u/HushedCanteen
  • My wife is now stressed, trying to herd our kid away from the hallway chaos, and her mom keeps following me like a ghost, whispering little speeches.
    via u/HushedCanteen
  • I finally stopped near the book fair tables and said, louder than I meant to, "You are not his guardian.
    via u/HushedCanteen
  • Don't ever say that again, to anyone. It's weird and it confuses people." A couple parents glanced over.
    via u/HushedCanteen
  • She got teary immediately and said I'm "trying to erase her" and that she "only stepped up because someone has to." That part made me snap because it's implying we don't.
    via u/HushedCanteen
  • I told her if she wants to be included she can act like a normal grandparent and stop playing martyr.
    via u/HushedCanteen
  • She stormed out and later texted my wife that she feels "unsafe" around me now and won't come to anything unless I apologize.
    via u/HushedCanteen
  • My wife says she agrees her mom was out of line, but also says I picked the worst possible moment and made the night tense for our kid.
    via u/HushedCanteen
  • I think the worst moment was her claiming she's his guardian in front of school staff like it's a casual title she earned.
    via u/HushedCanteen
  • AITJ? TL;DR: My mother in law introduced herself at my kid's school as his "guardian" and I corrected her publicly and told her never to say that again.
    via u/HushedCanteen
  • Now she wants an apology and my wife thinks I escalated.
    via u/HushedCanteen
  • MiraQuillFox NTA. She crossed a real line calling herself your kid's guardian, especially in front of school staff. That's not a harmless word choice..that's erasing you and your wife as parents. Timing maybe wasn't perfect, but the boundary was necessary and long overdue

  • Silvaria928 You have a far bigger problem...your wife. She is enabling her mother's poor behavior and someday it could very well come back and bite you both in the backside, as others have already pointed out. NTJ and I'd advise you get this situation straightened out through counseling before you both find yourselves in a legal battle for custody of your own child.

  • traciw67 Ntj. You need to inform the school that she is NOT the guardian so that she can't take your child from the school, etc. I would stop inviting her to so many things. She is really overstepping. Embarrassingly so!
    via u/traciw67
  • Life_Scratch_2807 Op I don't think you and your wife are thinking about the bigger implications. If in an event that she tries to legally claim your child, in an emergency or through grandparent right. Her statement will be used against you. She can claim, the school has me listed as a guardian and the parents approve. Even if you didn't, because you don't push back...she can claim she is guardian. Be very wary.

  • Sensitive-Eagle3641 NTJ. I felt relief myself hearing she "wasn't coming to things anymore." Enjoy it while it lasts!

  • Southern_peach87 NTA. There are serious reasons why schools ask to know who the guardian is. That could be a potentially dangerous situation. She lied and she deserves to be called out in front of the school staff. I wouldn't even put her down as an emergency contact or as someone who could pick my child up, if I was you. She obviously doesn't have respect for your decisions, school policies, and even laws pertaining to your child.
    via u/Southern_peach87
  • Quirky_Difference800 Never, ever apologize and keep your child far from someone that's trying to erase you. Also, time for wife to choose...her or your marriage. You're going to resent her if she allows this much longer.
    via u/Quirky_Difference800
  • SheepherderEmpty2481 It's time to have a real talk with your wife. Don't let grandma be around your kid without her having to apologize for her very, deeply disturbing behaviour. She created this whole mess and you handled it correctly. Having a relationship with a grandkid isn't something you "just have", it's something you earn, especially when she handles her relationship with you and her daughter so badly. She is not a guardian, you and your wife are. NTA.

  • Connect_Courage2329 Why do people always say it. wasn't "the right place" or "right time"? Your wife is the J. She should've stood by you in the moment especially considering by your account there has a been a buildup leading to this. I do agree though that you shouldn't have at school, but only because this should've been squashed well before your son was even close to 6 years old.

  • witchofwestthird You don't just have a MIL problem, you have a wife problem. She needs to shut down that shit, like yesterday.
