Am I overreacting?

Long story short, my MIL and I got into a small argument in which it somehow escalated to the point (without me thinking it was this bad) where my husband said he would take my daughter when she was born, to go visit his mom on his own without me. She lives in a different state and I asked my husband if he seriously thought I would let my baby (whom is my first child) go without me especially when she'd be so far away? He said "im not allowed to take my baby places?" & I said "not without me, especially to another state"

I asked sincerely if he thought I couldnt be civil enough to go visit his mom because I want her to see her grandchild but my baby goes nowhere without me, to which he replied "ill just put u up in a motel while she visits her grandmother" which implied to me that i was somewhat allowed to come but he and my daughter would stay at his moms house while I'd be left by myself in a freaking motel for the weekend.

I was SO upset that he would choose to leave me alone without him and my baby and was accomdating his mom and not seeing how I could be upset at his suggestions, but he doesnt see it that way.

Dont know if im hormonal and overreacting or what :(
