re: I have a 3 month old baby that refuses to sleep when he's tired

My oldest, I used to have to hold her and walk around. I’d do 800 laps around the house, it felt like.

My youngest, I’d have to sit in my lazyboy holding her a certain way.

Overtired is 100 percent a thing. Think of how grumpy you are when exhausted. Babies are no different. .
