I have a sitter-upper. We figured out how he was doing that. He would go from laying flat out on belly to knees & tuck them under him till he gets to sitting on his butt. He is also doing a funky crawl. Using his right leg to crawl with his left Knee. Too funny. But he will only take about a couple steps before he is done..... We think he may just walk shortly afterwards. He did try to stand up yesterday without holding onto anything. He fell over, looked at us, laughed, & sat back up. It was too hilarious. Weight last night was 202.2. Gained 2 oz. That's all for now.
