Mr. Mobile

Sebastian has made humongous progress in his mobility in the last few days. He can now crawl on all fours (slowly; he still prefers to commando crawl because he's so fast that way!), roll back to sitting from crawling, and pull himself up onto his knees or up to standing using an object. It's so fascinating to watch all of it unfold so quickly! Of course, his sleep is suffering - the poor guy is practicing in his crib at 4 am!
