My LO is 12 weeks and seems to be going backward on tummy time. Two weeks ago he was holding his head up really well and could roll halfway. One time he ruled completely with a small nudge. The past few days though he just lays there for a few minutes and starts crying bloody murder. He doesn't even lift his head. The babysitter has said he hates tummy time so I'm worried she's not doing enough. Is it possible for them to regress without enough practice? Should I be worried?
