I did try to do a search but perhaps am not using the correct search string (medication + vacation). If you guys could send me to the right place, I can look around. I'm concerned about my grandson who just turned six, on Concerta, and he's strong (incredible at gymnastics) but so thin and eats really poorly. He's not catching up with his calories at breakfast and late dinners. He does take a multi-vitamin and an Omega-3 supplement. He goes to bed early and sleeps hard, so just can't find time to get the food in. He acts hungry and interested in his lunch and dinner, then takes two bites and pushes it away. We've tried lots of different things, even high calorie power shakes, and he simply isn't interested. And his food preferences have really narrowed down. I've Googled it and there are differing opinions, and it all comes down to what's best for the child. He's been on Concerta since last November and it (along with many other things we've learned to do--and not do-- along the way) has helped him so so much. It used to be part of the accepted treatment to go off the medications to let kids catch up on their growth, but not as much anymore. Thanks for any thoughts, advice, etc.
