Why do you feel the need to have him eat off the kid menu? In my opinion a kid menu is a bad idea because it brainwashes kids to think that they have to eat a certain kind of food...namely junk food. Kids don't need to eat pizza and mac and cheese because it's just not healthy.
Out son is 10 months and we have no problems getting him to eat a huge variety of foods BUT we will not be giving him anything with salt, sugar, or processing. I cook everything he eats from scratch and it's always 100% organic.
There are lots of healthy options.
For protein my son eats chicken, sardines, salmon, eggs, and sheep's milk plain yogurt.
Veggies have included kale, chard, broccoli, carrrots, beans, peas, sweet potatoes, pea shoots, kidney beans, asparagus...you name it, he's eaten it.
We also give him whole grains like quinoa, amaranth, farro, brown rice, and oatmeal.
There ar elots of healthy options available and it never has to get boring. Just don't think for a minute that because he's a kid, he has to eat typical "kid foods" which are packed with fat, salt, preservatives, and sugar.
