Jack has always had awesome head strength. Since he was born, he's been able to keep it up for a little while. We also burp him upright on the knee so he gets lots of practice. Now he can hold it up for minutes at a time. But he HATES tummy time. Might be because of his reflux...not sure. However, we got the boppy out and that seems to help! Here is one of the 1st successful tummy times - thank goodness!
