Hi everyone,

My baby is 4 months and does ok at tummy time, but not great. She does this weird thing where one of her arms stays flat to the side and alongside her body with her palm facing up as opposed to putting both arms ahead of her and pushing up on them.

Her left arm does well and stays ahead of her and she pushes up on it, but her right continues to lay flat as if she were swimming. If I move it, then she goes great and pushes up on both arms. Is this normal?
