Apparently this is unreasonable of me, and i'm coming on here for an opinion if i really am being unreasonable.
I have a DS that's just turned one, im a lot more relaxed with him being around others because we've tested almost all allergens and so far he's not reacted to anything and overall has good health, so we're not overly protective parents (we of course are, within reason).
However, when it comes to leaving DS with MIL, im always hesitant because she doesn't know how to respect boundaries. If i say "no" to certain food, she will insist and continue to give DS whatever it is i've said no to. For context, Im not a strict parent when it comes to what he eats, I will let him enjoy treats, especially when we're eating and he's looking at us (again within reason) but she takes it too far, offering him endless cakes/sugar/even coffee. she will give him an endless amount of espresso.
Most recently DS has been taking an oral antibiotic for what is believed to be a mouth thrush. Could be from him putting everything in his mouth, but i've also said to everyone "no one is to give him kisses on the mouth" in hopes that she'll respect it. Along with that, ive said "no giving him sugar because doctor said to avoid it in order for the thrush to calm down as it feeds off sugar and only grows out the virus/bacteria" but she says that's not true, and continued to want to give DS a custard tart.
I've started to think if she's like this when i'm present, she'll act worst when i'm not and i'm starting to not want to leave him with her. i've been told it's unreasonable that i'll let him be with others, including my own parents, but feel uneasy with her, but it's a matter of her overstepping boundaries constantly.
Is it unreasonable of me to think this way?
