Am I overreacting??

Sara

So, my MIL offered to babysit as a regular weekly thing. She started for the first time last Thursday. She came to our house, picked our baby up (which I wasn’t too excited to begin with letting my baby be in a car with someone else, but I work really early and my husband too, so there was no option) and the arrangement was she would take him directly to her house and I will pick him up around 3:00.

When I get there, she starts telling me how they went to visit her mom and then they went to wal mart just her and the baby. She didn’t ask nor told anyone, I had to control myself and when I mentioned to my husband that it is not okay for ANYONE to take our baby anywhere without asking us first, that I do not like this and I don’t want my MIL or anyone else for that matter, alone in the supermarket with my baby or driving around with him in the car, that that was not our arrangement, he tells me I am being over dramatic, that I am overreacting and I should let go a little bit, that nothing will happen and we should trust my MIL and her judgment. It is not that I don’t trust her but I want to know where my baby IS, I need to be asked and she violated our arrangement. Am I insane? Am I overreacting? We are still learning to parent since this is our first and I would like to be on the same page with my HU but, I feel he is not overreacting enough, could that be??
