Tummy time

anneke

Hi everyone! My boy is 5.5 months and when he does tummy time he keeps on putting his arms next to him, it looks like he is flying 🤦🏼‍♀️ is it normal? How do I fix it? He does roll occasionally from tummy to back but not a lot and he hasnt quite mastered the back to tummy? Any tips would be highly appreciated :)
