My dd desperately wants to feed herself. She doesn't want any purees or baby cerals or mom putting finger foods in her mouth for her. The problem is she's not so good at picking things up unless they are like a dry cereal. Fruit is too slippery, etc. I know she's not getting enough solids to eat right now because she is waking up in the night starving for the boob. Any suggestions on easyto pick up, but nutritious, finger foods?
