Hi, I have twin 15 month old girls, so I'm right there with you. My girls still aren't big into eating meats (occasionally I can sneak it in something like Chicken Lasagna, spaghetti or regular lasagna). So I use other protein sources - they love black beans, cheese cubes, yogurt (I mix mine w/ applesauce to sweeten it a bit for them) & occassionally eggs (but usually not). Here's some things my girls love
Breakfast - blueberry or regular pancakes, applesauce, yougurt, cheerios, peaches, mini-quiches, pears (softened), apples, bananas, Nutrigrain type breakfast bars (if we're on the go)
Lunch - grilled cheese sandwiches or cheese quesidillas (sometimes I can sneak other veggies or a little shredded chicken in) cut into small bites, peas, carrot cubes, any of the above fruit, dinner leftovers, black beans, pieces of turkey or chicken or ham
Dinner Ideas- spagetti, lasagna, chicken lasagna, cubed sweet potatoes or carrots, peas, pasta, beef or cheese ravoili in tomato sauce, french fries (ugh, in a pinch, but they love them of course), drained chicken noodle soup (I make mine with the Ditalini shapped pasta & they love it and gobble up the bits of carrot, onion, celery and chicken with it!), fruit, black beans & rice
My girls drink whole milk all day until they get their 17-20 oz in and then water with a splash of juice (apple, prune, white grape, fruit/veggie juice, etc)
Desserts or snacks - gold fish crackers, graham crackers, club crackers, cut up fruit (grapes, apples, bananas, peaches, pears, etc), animal crackers, cheerios, crackers w/ a thin spread of peanut butter
Hope that gives you some more ideas!
