my 5mo certainly can prop on his elbows during tummy time, but for whatever reason he is now refusing to. Unless there’s a toy in front of him that he can grab, he puts his arms out to the side then fussed (elbows still bent, not arms straight out like an airplane) & won’t bring them back under. He does this even if propped on something under his chest. I repeatedly move his arms back under for him, but if I don’t keep my hands on lightly on him like a boundary, he doesn’t hold the position.
Is there anything else I can be doing to help him? I’m really trying to get him to start pushing up on extended arms by doing baby planks to strengthen his arms. I hold his arms straight during the planks but he fights me. He just wants to grab whatever is in front of him even if it’s things he “can’t” grab like high contrast cards, a mirror, etc.
(On a similar note, he refuses to practice tripod sitting. He’ll push is arms back when I try to get him to bear weight & push off his feet)
He has mild hypertonia in his arms but with stretches we’ve done since he was 2mo, he’s actually pretty limber now
