4 month sleep regression getting worse!

Em

I know I've already posted about this a couple times but this sleep regression is getting worse! My daughter literally starts crying the second we put her in her crib. She could be in the deepest sleep too 😕 What in the world do I do? My husband and I have been at this for 2 hours already and we have not successfully gotten her down. I anticipate it is going to take a lot longer too (if not all night). SOS.
