Y.R.
My daughter is 18 months and became very picky about what she would eat at about 15 months. She did not want anything cut up and she would not eat anything unless she could feed herself. (problem was she was not very good at feeding herself.) We came up with a new version of hotdogs.
Whole wheat hot dog roll, with a banana inside. toppings were everything from jelly, peanut butter, wheat germ or granola. My 5 year old son has been now eating them as well.
If you use the peanut butter you end upwith a pretty balance meal wheat, protien and fruit all in one.
