Hi LauraCarlos. I hate to hear this about your son! It is good to hear that he has responded well to steriods and hope you can get him into remission.
My son was 14 when he was diagnosed so his situation may not be exactly applicable. Steroids were a miracle for him. His issue was getting off of them, so the dr added in full EN as a way to help ease the transition off steroids and onto what we thought was going to be a maintenance med. The drs he saw had lots of experience with EEN, EN, 100%, 80/20, cycling, and were very pro EEN in situations where they thought the patient was able and willing to comply. He eventually transitioned to about 80% EEN and 20% of calories from Specific Carbohydrate Diet, and slowly moved to where he is now, at about 30% EEN and 70% SCD. His labs, MREs, scopes and biopsies showed slow but steady progress and here we are a year and a half later, in remission.
It wasn't an easy journey. We tried about 10 different formulas to find one he could tolerate and would drink. Some were prescription (he was fondest of Peptamen Jr vanilla) and others were not. We adjusted our family eating behaviors to lessen the blow of him not being able to eat and took some other steps to help with the fact that really everything in life involves food. We had to negotiate, threaten, bribe, praise, encourage, etc and my husband even drank with him for a week. There is also the time investment of the extra monitoring our drs required because we used this treatment.
I have had a few others on this board contact me about EEN. I think one mom had a 4 year old. I'll check back in with her. The biggest piece of advice I have is to make sure you are working with a GI who has had success and knows how to work EEN with such a young child.
I'm sorry you had to join us, but hope to hear some good news about your baby soon!
