Olive, DD always wakes AT LEAST 3 times a night (and that's between about 9pm and 6am) I never knew I could survive on such broken sleep but I actually feel ok lately, she has trained me well, lol.
My DS is the same, and a few weeks ago I was feeling really good despite the months of broken sleep... However, recently it has caught up to me again . Really struggling these days. Hope you keep feeling good.
