Just read a research finding in Parents mag that when kids were served larger portions of veggies, they ate more veggies. Maybe that's why a jumbo portion of broccoli went over so well in my house recently.
I had cut off small portions for each of my kids. Then they saw the gigantic piece left on the serving plate. My son asked for it. I thought, why not? Looks fun. And it was. Both kids ended up eating giant pieces of broccoli, and ate more than I've ever seen them eat before. Cool!
