My (nearly) 14 week old son keeps on falling out of tummy time. He had been doing quite well on tummy time, ie: propped up with shoulders above elbows and could stay there for a few minutes tracking whatever toy I moved in front of him. But since about 12 weeks he keeps on ‘falling’ out of that pose as if his arms aren’t strong enough to keep him propped up or he’s in pain. He tends to put both arms out in front, slightly superman, and then face plants. I pull him back into the propped up pose but have to hold his hands to keep him there, otherwise his arms fall out again.
Some context - he’s had a double inguinal hernia repair at 7 weeks old and he has a cows milk allergy. Conscious both are tummy related so perhaps why he is doing this, but noted he could do tummy time perfectly 8-12 weeks so not sure why we seem to have regressed
Unclear as to why he’s doing this. Could his arms be in pain or does this suggest weakness we should be concerned about?.
