Oh, there’s definitely hard parts of having kids—but changing diapers isn’t really one of them.
Highly recommend getting a sleep tracker app.
Every baby is different so most of the advice you find won’t work, but if you try enough things you’ll eventually find something that works consistently. Or you might just luck out and get a good sleeper.
The thing I remember being most annoyed about was cleaning all the bottles. That was really obnoxious.
