It usually takes three or four attempts to get one spoonful down the hatch, but we are trying out the baby food thing. So far she has had whole wheat cereal, banana, avacado and jarred sweet potatoes. She has liked all of them.
Her first time eating sweet potatoes (it was also her first time eating baby food from a jar).
I guess I can't call sitting up an actual "trick" when she really can't do it without assistance. We have been practicing though and she is getting more steady on her own each day. We still have a ways to go, but it is fun to see her face light up when she can sit across from us and play.
Using mommy's legs to balance herself. She has a habit of throwing her head back when she is being held, or practicing sitting, which makes mommy really nervous. This is going to be a hard habit to break.
