My son is 7 and has had a 14 fr G-peg since he was 1. He's been fed only Pediasure for 6 years! We have recently detoxed him from this "food" and have got him on the road to recovery! We give him pureed food, but have difficulties passing it through the current size peg...with a continuous feed system. Would greatly appreciate anyone's advice and experiences increasing peg size and bolus feeding. I imagine that continuous feeding is out of the question due to the thickness of the food. Please help...we are facing some serious nutritional challenges and weight loss!!!

What sort of blender are you using? I mean, you could go up on the french size of the PEG, a 14 is kind of small, but dilating the stoma can be rather painful. May want to try move of a high powered blender and a different proportion of liquid to solid food that is being blended.
This is the recipe someone I know who does the blended diet uses...
3/4 cups grapes
3/4 cups whole cranberries
1 1/2 cups lettuce
5 oz turkey (from Thanksgiving)
2 1/2 cups of brown rice (slow cooked)
2 cups soy milk
4 tsp flaxseed oil
and I believe they use a Vitamix blender.
