The Incredible Cookie-Dough-Eating Hulk

One of the biggest struggles we have with Mr. Busypants is his diet. The kid won't try anything new! Here's a history of his eating:
Age 1: Mr. Busypants is eating all baby food. The only things he didn't like are Stage 3 and that nasty "meat" that Gerber packs into those tiny little jars. As we transitioned to regular food, he took a liking to French toast sticks but not waffles. He at FTStx every morning for about 2 years. Other notable dietary delights:

He tried his birthday cake.

He refused all fruit

Mac-n-cheese was a favorite.

Mozz. cheese sticks

Spaghetti pie and a couple other noodle shapes were acceptable (yes to wagon wheels, no to spiral pasta)

Canned green beans and carrots.

Cherrios

Milk, but only white. Some juice, but not much. Lactaid or soy milk ok.

Chicken nuggets (Aldi brand, Wendy's, BK, McDonalds)

Around 18 months there's a shift.

• Mac-n-cheese was a favorite. First any brand (Easy Mac, Kraft Original, Annies). Then only Annies.
• Mozz. cheese sticks (on and off)
• No spaghetti products, canned green beans or carrots.
• Cherrios
• Milk, but only white. Some juice, but not much. Lactaid or soy milk ok.
• French toast sticks still ok (original or cinnamon).

At the 3 subject becomes increasingly more picky.

• French toast sticks--no way!
• Mac-n-cheese--can melt cheddar cheese into it if he's not looking.
• Cherrios Cherrios Cherrios
• Milk, but only white. Some juice, but not much. No Lactaid or soy milk.

His diet didn't change much through Kindergarten, although he took a break from Annie's Mac-n-cheese and when we re-introduced it, he would only eat Kraft. For a while, I could just throw the ingredients together hap-hazzardly. More recently; however, unless it is made to the exact specifications of the box (and even then sometimes its unacceptable) he will whine: "Ooohhhh! It's different." Nobody is quite sure what it's different means; we simply understand that on occasion, for no particular reason, it simply is.
Mr. Busypants, over the years, has developed an obsession over cookie dough. It's like crack for autistic Kindergarteners. No kidding! We do cookie dough two ways: 1) I buy the Pillsbury mix and we make it; he spoons it out to his heart's content. 2) Pre-packaged Pillsbury pre-made cookies or, if available, the pre-made cookies with the holiday stamp in the middle (soccer balls, pumpkins, Christmas trees, snowmen, hearts, four-leaf clovers, Easter eggs, and flags.) Either will do.
Recently I noticed he developed a greedy, addiction-like, all-consuming need for cookie dough. I'd get the package off the top shelf and he'd raise his arms and pull me down until that dough was in his reach. Then he'd greedily rip open the box and stuff them in his face, stealing as many as he could before I wrestled the box from him.
It changed him. He is mild-mannered Bruce Banner most of the time, but when that cookie dough surfaces, he becomes as green as the Incredible Hulk.
I tried to use cookie dough for good. I really did. I'd make the mix and then break up Flintstones vitamens with a meat hammer, then mix 'em in. The one time I tried that, he walked right up to it and within a half a millisecond declared: "It's different." It's like he could smell the difference down the hallway.
Most food these days is subject to a sniff test. Mr. Busypants trusts no one and can never be too careful.
Stangely enough, he does have some areas where he lets his food guard down. For example, at school he developed a taste (finally) for chocolate milk. I rejoiced, thinking I could sneak more stuff in chocolate milk. I was even surprised that he tasted (and liked) my chocolate Slimfast, so I tried Ovaltine--nope--and Carnation Instant Breakfast--It's diiiiifffffferentttttt!
And Go-Gurt is his latest love. Oddly enough, he'll eat any flavor of those sugar-infested, flurescent, tubbed delights. Any other yogurt and you can take a hike. Yogurt Cherrios are acceptable as well.
Now his sister, Miss Chattyshoes, never met a meal she didn't devour into those chubby little cheeks. She'd knaw my right arm off if that was the only available meal. She eats anything and everything and she likes just about all of it. She also likes her brother: both to emulate and aggrivate. The other day Mr. BP left his French toast sticks unmonitored (those re-appeared into the diet in early Kindergarten), and she was there lickedy split. And as she slowly brought a fork full of those sticks to her chubby little face, she waited for the fireworks.
Mr. Busypants didn't disappoint.
I have so much more to say on this subject. I'm sure it will be an entire essay in the Mr. Busypants book. But that's about all for now.
