Ugh so frustrating. My LO is 14 weeks, and everytime I put him on his stomach all he wants to do is eat his hands instead of doing "tummy time" and practicing lifting his head up. He can hold his head up good when he wants to but that's rare. How can I get my son not to chew on his hands so much and focus on lifting his head more? I've done the toys and getting down to his eye level but nothing has really gotten his attention to quit the chewing.....does that mean he might be teething? He's not overly cranky or running a fever.
