Hi moms!
I just want to say that you guys are doing a terrific job. It's great to see parents actively involved with their children's diet and health! You guys are promoting a healthy diet and an active lifestyle, which is simply what health professionals recommend for children. During my rotations in pediatrics and family medicine, we would always advise parents with young children not to be concerned with weight loss and to especially not have the children concerned with weight loss. We track their growth on a height and weight chart and encourage them to be active and eat healthy and usually they will grow into their weight. Patience is key.
I'm not sure if anyone has already suggested this, but letting kids have a choice in what they want really helps and diversity in foods is a plus (ie. let them pick out which fruits and vegetables they'd like in the produce section).
