It is hard, I do get stuck feeding my almost 3 year the same thing. But we do eat the night before leftovers a lot. Plus he loves Ham, Farmland makes little Ham pieces that he loves and to make it fun I put pretzels stick in each piece. I could put a little pretzels stick in anything and he will eat it. He thinks it is fun.
Chicken patty or nuggets
Ham
Sometimes Hot dog but not a big fan
He doesn't like sandwiches but will eat grill cheese.
Summer sausage
fish sticks
he loves the little carrots, cucumber pieces, red pepper pieces(he loves to dip these in salad dressing) peas, green beans, beets, corn, broccoli. You can buy the freeze dried fruits and veggies like peas etc. He used to be sooo picky but would eat those and I kept offering the fresh stuff and now he eats almost all fruits and veggies. You just have to keep trying and be creative. Know your kid and what they like and incorporate it into their food. My son loves trains (Thomas the train) and we told him how asparagus grows by the train track and now he eats it. I told him how I chopped the broccoli tress down for him and he loves that story, etc...
Apple slices, watermelon, strawberries, grapes, sometimes banana but not his favorite, cantaloupe, pineapple (loves the little fruit cups too) raisins, craisins,
He loves nuts too, cashews, pistachios, etc. My husband and I have no allergies nor any family memebers so I wasn't to worry about that. Great nutrition in there and has protein when he doesn't want meat. ( He doesn't like peanut butter though :(
He loves crackers, sunchips, chex mix, any type of pretzel, so many kinds, I mix it up. He loves to crunch on stuff while eating lunch too.
McCain makes little potato smiles and hash browns things, I put those in the toaster oven. Or toast, he loves toast with Parmesan cheese and butter. Weird but he loves it.
Yogurt and Chocolate milk. I breast fed him and he would never drink white milk. He use to love cheese but now he won't eat it alone, like cheese pieces. So many kinds of yogurt but he likes what we eat. Also lead by example they really do follow what we do. Eat what she is eating, vice versa.
Like I said leftovers help break up the monotony, spaghetti, pork, what ever we had the night before. The only time I don't serve leftovers, if he didn't like it to begin with. (he is not a big Mexican food fan but me and my husband are I still make tacos etc and he will eat it but I don't make him eat it for lunch when he can easily have something else.)
Good luck,
M.
