Crawling and pulling up

Sorry it has been a while since the last post. Ethan has been changing at a blinding pace the past couple of weeks! He has four teeth now. Still having some issues with noisy breathing most days. He is getting very good at crawling, not letting obstacles get in his way- he just goes right over them. Ethan can crawl from one room to another now, so we are getting a true taste of how much babyproofing we need to do immediately. One week ago, while Ethan was having a playdate with his friend Christopher he went from a crawl position to sitting for the first time. Then as the week progressed his crawling took off and he learned to pull himself up- on laundry baskets. We have to be careful that he doesn't go pulling himself up on laundry baskets unless we are holding them, since they are light. He has been having many more bumps on his head these days from his new found mobility. He even had an "incident report" at school when he was "playing inside the toychest and bumped his head". It is getting very difficult to change his diaper these days too- he immediately will turn over and start crawling away, diaperless. We are just amazed and full of joy watching him blossom. We are so proud of our little guy.
