DS is 3, and currently has a PEG tube. He's booked in to have it converted to a button, but surgeon wants to discuss it first, he thinks we might find sticking with the tube easier. Please can anyone tell me what their experience is, and is there anything different/better-or not- about button v's tube. Is there any reason that a tube has to be converted to a button, or can tube stay indefinitely? It's been in 2 years already. Thanks.
