My son was diagnosed at 16. He was given a choice of steroids or 6 weeks of EEN. But, it was made very clear to us that his dr preferred EEN over steroids as a first treatment. As Jacqui said above, it was difficult for him to go 6 weeks of no food. He ingested his formula overnight thru an NG tube. As he was allowed clear fluids (clear pop, gatorade, broth, freezies, jello, etc.), he would take broth to school so he could have 'lunch' with friends and I arranged for the school to keep freezies on hand for him. At dinner, I didn't make him sit with us but he would have a bowl of broth as a 'dinner'. It was hard and, as he was ingesting all his meals overnight, he would be hungry in the late day/evening. But, as it was very much his choice to do the EEN, that helped.
He also had one week of Flagyl thru IV while he was in the hospital.
Whether it was the flagyl or the EEN, he felt hugely better within a week. Within two or three weeks, he was back to regular school schedule, playing on two hockey teams, etc. (although it took longer for him to regain the lost weight and his strength/endurance).
Once the six week period ended, his maintenance treatment was to continue with the formula at half dose (1500 cal/day, still overnight) and gradually add in regular food. We continued this for two years. His only med was nexium. He felt and looked great and, over the two years, gained approx. 40-50 lbs (but, 'good' weight - muscular, deveopment, height, etc.). However, MRIs continued to show some simmering inflammation.
Upon transfer to an adult GI, the new GI was adamant that the simmering inflammation would eventually cause complications, perhaps even surgery. He strongly recommended remicade. As my son was 18, the choice was his to make. I made sure he was aware of the risks both with and without the meds and let him choose. While I hated the idea of giving him these meds, I also understood the risks of going without. And, as he would be the one suffering the consequences of undertreating the crohns, I couldn't ask him to not take the meds.
These are difficult decisions. Do ask questions and learn as much as you can. The more familiar you are with the choices you have, traditional and alternative, the better you will feel about your decision. As hard as it is, try not to let emotion get the better of you... when it's your child, it's easy to see the risks in bold, flashing letters and then kind of skim over how small the risks really are. I've said it here before, we allow our kids to take all kinds of risks in order to improve their QOL - swimming, driving as teens, playing 'rough' sports like hockey, football, etc. - and we do this because it improves their QOL (and, no one is handing us a sheet listing the risks as they walk out the door and asking us to sign off!). While it's not exactly the same, getting the right treatment will also improve their QOL.
