Anyone know any different ways to do tummy time? My son is 3 months old and he is strong with his head,he just can't hold it up for long. He's getting frustrated because he wants to keep his head up and he also wants to sit up and roll over.
He isn't too keen when I put him on his changing mat to do tummy time. He likes being lay over my knees but I'm just wondering if there's any other ways to do tummy time x
