Hehe I took Ellen out of the high chair a bit too early the other day and she went around the floor gathering up all her dropped cheerios and eating them!!
Re: crackers, I give her unsalted saltines, *occasionally* goldfish if I have them, graham crackers, and the other day MIL had some cookies that are called Maria's Galletas and they are very mild and the ingredients very good so I give her those too. They're kinda like shortbread cookies, but not quite as sweet. Basically anything that's not too sweet or too salty.
