I can somewhat relate to your problem. My 13 month old was a wonderful eater for about a month. He was eating pasta, meatballs, scrambled eggs, fruit, veggies, chicken, etc. It was great. Then he recently came down with a horrible head cold (coughing, runny nose) and I feel like I'm at square one with eating. Now he puts the food he used to love in his mouth, chew it a few times, and spit it out. It's extremely frustrating. Anyone have advice on that?
As far as ideas, macaroni and cheese is a great lunch along with chicken nuggets and french fries. I also made a huge pot of veggies (green beans, carrots, squash, corn, peas), noodles, and chicken boiled in chicken broth. He loved this meal and it was great because I was able to freeze portions for future meals.
