if you're keen to go down the finger foods route, i'd suggest maybe giving her some veg for her tea or somethin like that. also, they're quite good with strips of chicken and stuff, cos it sort of melts quite easily. at this age they dont necessarily need loads of food cos they'll still get a lot from their milk. have you tried pasta aswell? that goes down a treat!
i know katie's a lot older, but we give her toast in the morning, sandwiches and sometimes fruit for lunch, depending on how hungry she is, and we've started just giving her cut up food for her dinner, normally left overs of what we've had the night before, or pasta with tomato sauce! creates a right mess, but is well worth it to see the smile on her face!
