on the go!

On December 29, John Paul started crawling on all fours. It has made him so happy to be mobile. He even follows me from room to room. Of course, I have to keep a watchful eye on him. And then it was the next day that he started pulling himself up onto everything! The next day! He especially likes pulling himself up on the computer and in his crib (which is also preventing him from sleeping well. Does anyone have any tips?)
