Hi K.,
I'm a very relaxed mom about eating, probably to the point where some people would judge me for it, but what ever.
My son ate great as a toddler, I never fed him formula or canned baby food, it was all home made and fresh, so I thought he'd be a great eater, to my surprise he grew to be so darn picky, he lived off of noodles, hot dogs, corn dogs, cereal, and thats about it... But there were some things he loved, freshly juiced Orange Juice, probably because it was fun to make, "Trees" or Brocoli, because He'd pretend he was a dinosaur eating trees. And Carrots with Ranch. He hated cooked veggies which is GREAT with me, I think raw is better. Well we survived, slowly he started introducing new foods to his menue. I bought a better homes and garden child cook book, him seeing the pictures of the kids making food made him curious, they were on his level, and they were funky foods too, like peanut butter and bacon sandwhiches, so I let him plan his menue, we hardly ever ate the same thing together, I had my dinner and he had his, Is that right or worng? I dunno, but it worked for us, I would be so pissed if someone made me eat something I didnt want to eat, Make me eat Rhy bread today and I'll fist fight you over it (lol) so I wont do that to my son.
I bribed him now and again to atleast try something new, sometimes he would, other times he wouldnt. I switched from milk to chocolate milk, that worked for the milk department. and I'd give him flinstone vitamines (or what ever kid vitamin) But over the years, he's increased his menue so much to the point where now he eats what we eat, he'll even eat something even if he doesnt think its that good,(except peas, he hates peas)
He's 12, never gets sick, I cant remember the last time he had a cold, atleast 2 years ago, so I believe he's healthy, he's strong, he's gaining weight.
I would say just keep trying new fun recipes,and bribe if you have to, maybe get him involved in making the food will help, and give it time. He'll grow out of it, I think, I do have one friend who still lives off of mac-n-cheese, and he's in his 40's.
