My baby just turned 7 months and is not pushing up on arms during tummy time. Recently he just arches up with his arms behind him in almost a “skydiver/Superman” position and kicks getting very upset until we pick him up. He used to do fine pushing up on his forearms so this seems like a regression.

Do any moms have experience with this or see their babies do this during tummy time? He just started sitting without support so I wonder if he is just focused on this skill. I’m trying not to worry but feel like he should have more strength in his arms by this age. Any experience or tips on how to encourage him to push up on his arms would be much appreciated!!
