I don't get it why but I can't seem to wake up when my baby cries at night. It's been a week, my husband wakes me up when our 6 months old cries.

And he has to put in a lot of effort to wake me up. A 3 hour stretch at night is almost like I'm dead. I don't even know what happens at that time around.

I wasn't this heavy of a sleeper before but now it's this. What do I do about it? Husband can't sleep because of his cries and wants to sleep in a different room now. How do I manage this situation.
