We started after five months. We still started with cereal, but didn't stick with it too long because it was constipating LO. Now, we're slowly working through the vegatables - which she likes much better. She opens her mouth wide for the spoon. We've done squash, sweet potatos and green beans. We're on peas now (her least favorite so far).
TTC #1 since 6/08. Cycle #6 - BFP 12/22/08, EDD 9/3/09, DD 8/14/09 at 37w1d
We started at 5 1/2 months with fruits and veggies - bananas, avocados, pears, apples, and squash so far. It took her a few times to get the hang of it but now she loves it.
