Heidi learned how to nod her head yes a couple weeks ago. It's been great cause if she wants something she will just nod yes. And her nod involves her whole body...her head all the way back and then all the way forward which usually knocks her off balance because of the force she puts into it. So then last night she figures out how to nod side to side to say no. But now she can't figure out which way she wants to nod when she is answering you so she kinda nods in a circle. Mostly clockwise but sometimes counter clockwise. Very funny.
