Hi H.,
My son was a 24-weeker and we had many problems getting him to be able to eat enough to gain weight. We were given the option to tube him and chose not to. He is now 6 years old and about 30 pounds. We just met with yet another nutritionist a couple weeks ago for a new plan. He eats a TON and a wide variety of foods but just won't gain weight. We've had lots of other tests to see if anything else is wrong but everything comes back normal. So far he isn't a candidate for Human Growth Hormone.
The reason we chose not to tube was that we thought he COULD eat. We misunderstood the tube to mean he COULDN'T eat. We were also afraid of language and sensory issues that tubed children often develop. Our son is very smart, articulate and only has a few sensory issues (which is pretty amazing for a former 24-weeker).
I can't say that hindsight is 20/20 on this decision because we don't know if what we did was the right thing. What I have since learned is that children have a narrow window for which they develop their fat stores and by not tubing him, he got enough to survive and grow slightly but not enough to build those fat stores. After this last round of appts. and tests I asked the doctors and nutritionists straight out if he will ever have the chance to make that up. I didn't really get a straight answer because I think it is kind of a crystal ball type answer but one doctor did refer to it as malnutrition - which scared me.
So, I would caution you to not think about going back to the tube as a step back. You will notice in every area of a child's development that it doesn't go in a straight line forward - it is two forward, one back, three forward, one back etc. I would assess how your son is going with language/speech (may be early to tell for a 2 yr. old with cleft) and sensory issues. If he seems to be within normal realms, I can't think of any other issues that would prevent you from going back to the tube.
It IS temporary. He won't be going to high school with a tube - I guarantee you that. If the tube is a bonus for calories and not interferring with other developmental milestones, I would say go back to it for a while and reassess.
