J., if you haven't already found it, a great book is The Sneaky Chef by Missy Lapine. The local library has it or you can try the bookstores. Some of these recipes are truly hidden veggies and fruits. I have a 5 year old who was picky and still is on some days. She has loved all but 1 of the recipes I made.
You mention building a home business. Not sure if you have one already or not, but check out my website at www.juiceplus.com/+ht49010. Juice Plus is not a juice, but a gummies, chewable or capsule which truly has the nutrients from 17 different fruits and veggies and 2 whole grains. I will swear that this helped and took away my daughter's eczema at age 3. It would make sense as eczema is typically an immune deficiency and good nutrition solves a lot of immune function issues.
I'm not meaning to be a sales person here, but look at the medical journal published research on my website. I would also suggest you try the Juice Plus gummies or chewables for your little one. Our cells have memory, like after Halloween when you say you won't get in to the candy the next day, but you want nothing but candy that day because you have been eating it for several days straight. The same thing with fruits and veggies. If you can get it in the kids, then they truly will want to eat more fruits and veggies. I know it is unbelieveable, but it worked with my daughter. Plus, the children's research study with Juice Plus proves this as well. Just eating Juice Plus increased kids ages 6 - 16 eating of true fruits and veggies. Seriously, check it out from a nutrition standpoint, and if interested in the 'family discount' or a home business that can truly impact the health of others, let me know. My contact info is on my website. Check out the Dr Sears short video clip. He is awesome.
Happy eating of your veggies!
One last trick that Dr Sears suggests... put out a muffin tray with different fruits and veggies in it. Leave it out, put some dressing in the middle of it. Then just tell the child to try these when he is hungry. Don't pressure or say anything about it. Amazingly enough, the child will try things on his own. Set it out for several days. You'll be surprised that he'll eat things you never dreamed. HOpe that helps. :<)
