MIL doesn’t approve and said something stupid

LO is 4.5 mo, my MIL doesn’t approve of our bed sharing (has only expressed this to my hub and never directly to me) and is always asking about our sleep and where he’s sleeping. She was over and asking how we slept last night… she knows we’re going through the regression and have been for about 3weeks. I’m exhausted. I answered about the same as it’s been, waking up constantly and I don’t expect to be getting any sleep right now….

She responded “what about the crib? he probably just needs some space and wants to stretch out a little”

HUH??!?! I shook my head no…just no… I responded “maybe but he needs his mom right now more than he needs “space” whatever that means lol
