Not concerned, just curious. When could your LOs feed themselves with finger foods? DD is a little over 6 months, and has been eating solids for a few weeks. She's all about the purees, and will play with chunks of steamed veggies and fruits on her high chair tray, but has never once put one in her mouth.
She'll open up if I have a chunk in MY hand, and she puts all kinds of other things in her mouth (toys, her own fingers, etc). Just curious when your kids made the connection!
