My son is 4 months old now and for a few weeks he has been picking up toys and likes to play with his little hands. At first he didn't like tummy time and now he loves it. Give your baby some time, maybe he will change. You can also sing songs 😊
My baby is 4 months old now and has only just begun acting enjoying tummy time. She was the same, crying every-time I tried. Give it time and just keep trying ❤️ I found toys that light up were good for distraction during tummy time
3 months is still early but at 4-5 months what my lo enjoyed the most was mirror time with me (we cuddle in front of it and I do silly things he would laugh like crazy).
