Nathan turned 5 months old and yes, I'm hanging on to this basket! I am so excited to report that Nathan now rolls over consistently from his belly to his back with no problem. We are working on the roll from the back to the front and he's doing very well. He's also recognizing words - he knows his name, the word "up" and the word "in." Because he is so alert and pays attention intently I have begun teaching him sign language. Although, I don't expect he will respond for a few months. Nathan is also holding his bottles - we began working on this about 2 or 3 weeks ago and he has made tremendous progress.
In therapy, Nathan is working on his trunk control (or core). We now play with toys in a sitting position and work on having him reach to grab them. This developmental stuff sure is fun business!
