It's been a month in the making but Spencer can finally sit unassisted. It seems to me that many babies sit by about six months - Spencer is seven and a half months now - but he is also stabilizing a considerable amount of weight. He has even figured out how to catch himself before falling over!
Given his size I do wonder what Spencer's development we be like when it comes to crawling and walking. Will he bum schooch like Eloise or actually crawl? I don't see him as an early walker, which is a good thing, but I also don't want to be hauling all 30-ish pounds of him around until he is 17 months old. For now I'm good with sitting.
