savanna is a slow developer i think, she sits by herself if you sit her up and leave her(of course not un attended)but she just started too, she rolls all over the place, but she doesnt crawl and doesnt try that hard most of the time, and she has said mama but only when someone else is holding her and she's crying super bad, and she reaches out to you when she wants you to hold her and isnt cutting any teeth. what do you think? she'll be 8 monrhs on the 9th
