Getting your kids to gain weight is always a challenge. You just have to take it slowly. If the docs just mentioned a feeding tube and haven't given you a chance to try and get some weight on him first and that's what you want to do then just tell the docs. I know some people probably wont' agree with me on that but you know best right now what you can handle. My girls are older, teenagers. My oldest wasn't diagnosed until age 3. She's the one that's always had a weight problem. The docs didn't start talking feeding tube until these last two years when she was 15yrs. old. By that time, she was set in her ways and absolutly refused to have one put in. Being a teen she was able to try a medicine generally used for cancer and HIV patients to get them to gain weight. It worked for her really well. But your son is not old enough to use it. Here is what they told us to do when she was little. Add butter, margarine to everything. Veggies, rice, potatoes etc. Use lots of gravies. Whole milk only and make it super milk by adding powdered milk to it. YOu can also use powdered milk added to your mash potatoes, then the butter/margarine, and whole milk. Puddings are good too. Peanut butter on crackers. Fast food has tons of calories. Many places have calorie booklets now. Wendy's Frostee, the small one, has like 370. Ice cream. I know he's only two and can only eat so much. Chicken nuggets from KFC or the popcorn chicken even better. I don't mean to say eat only fast food, heavens no! In the summer, we tried one frostee a day but that got to be too much so we changed it to three times a week. Hope some of this helps at least to give you some ideas on where to get throw in some extra calories. And tell the docs if you want to try and get some weight on him first before thinking more in depth about a feeding tube. But I have heard that they do wonders. Liza
