Reagan has just started to crawl up on all fours, doing the commando crawl only half of the time now. She has two teeth on top and two on bottom, and she loves to sit in her highchair at meal times with us and eat whatever we're eating. She still isn't sleeping through the night, waking once, often two times a night. She is the worst sleeper of any of my babies, but also the easiest when it comes to entertaining herself. She doesn't seen to want to drink much more than 6 ounces from her bottle most times, and is far more interested in what is going on,around her than actually sitting still to eat. She has started growling at funny moments, and has occasionally given a single loud shriek when she is playing with her siblings. She can totally sit up herself with no problem, and enjoys crawling everywhere in the house she can go. She recently learned how to get up and over the step up from the living room, and has to be corralled in the living room with chairs and pillows if we want to keep her in one space.
