I never slept well even as a newborn. They actually gave my mom phenobarbital to sedate me when I was a few months old but it scared her when she tried it because it sedated me far more than you want to sedate your infant.

As long as I've been on meds I've needed multiple meds to sleep and generally at a fairly high dose of both or all.

I think it was the first sign of bipolar for me.
