Anyone with complicated relationships with their in-laws will tell you that boundaries are the most important thing in keeping them on good terms. Even those who don't consider their relationship with their in-laws complicated would probably agree that boundaries are essential. There is simply something about our in-laws' wiring that is bound for trouble, and there is only so much you can do to avoid it.

When children are involved, and by that we mean children of your own, if you haven't established your boundaries yet, you might find yourself regretting that. As soon as you give your in-laws grandchildren, they become completely different people, and not people you usually want to have constantly around your kids.

So you must set ground rules. When and where they are allowed to visit, for how long, what they can or cannot do with your child, and what your absolute red lines are. Then, and only then, should you allow your in-laws anywhere near your baby; otherwise, don't say you have not been warned.

    "WIBTA if I told my fiancée and my MIL I will no longer buy groceries for my baby."

    So backstory before I get into it, I (23 F) gave birth to my son last summer. My MIL was VERY involved in my pregnancy which I was very thankful

    EDIT: I may have not specified this, but I will still buy my son his groceries for our home. I would have my MIL use/buy food instead of me packing his meals.

    PrestigiousPie8014 This childcare arrangement just isn't working. Can the babysitter be at your house during the day?

    purplstarz The fact that your babysitter is cleaning for MIL and feeding your child MIL's food when you told her to feed the food you provided, means your babysitter isn't willing to go. against MIL's preferences for

    for you. It will continue to not work for you as long as your child is being watched in MIL's home. Change to your house. That may mean changing babysitters.

    Hidden Vixen21 So. Your child is at MILS house. And is being fed healthy appropriate food. It's just not your food she is feeding your kid?
    via Hidden_Vixen21

    Either you are being way to demanding and have some over the top expectations. Or you need to stop letting your kid stay at MILs house without you there.

    Possible_State4774 OP Some of the food she has offered and will feed is gerber. I don't want him eating that since there been soo many recalls for metals being found in the food or choking hazards

    NoFlight5759 Wake up earlier and drive to your mom's would be solution 1. But, you now have a kid with this man better buckle up this will be the norm for a minimum of 18 years. I'd advise not getting married. NTA if you get your a up and drive it's 30 minutes not 2 hours each way.
