The video below was created 6 April...until very recently, Emma could not sit without support! Now she can sit for several minutes if we put her "in position" first.
It's very hard to catch Emma with a camera while she's counting, because every time I pull out my camera she sees it and stops. Below is a very brief (and very amateur video) of Emma counting on the evening of 21 March:
For some reason she used to leave out the number seven on a regular basis! :-) She does say "seven" most of the time now....in fact, lately she has been counting all the way up to twenty, but I haven't managed to get video of that yet.
