Rolling/push ups

Rachel • Mommy to Anniston 💕 4/1/18

Anyone else's babe not wanting to roll from tummy to back? He keeps rolling in his sleep (back to tummy. He hates tummy time) and then gets mad and wakes up but can't roll from belly to back yet... he also can't do "push ups". I try to show him but when he is on his tummy he puts his arms straight out to his side. Any tips? Is this normal?
