My son Thomas was born 7 weeks early and weighed in a 4 lbs 2 oz which we were so excited about b/c he was thought to be only 3 1/2 lbs in utero. He breathed on his own and held his temperature very well out of the incubator so basically he was classified as a "feeder and a grower" Charming isn't it :) He came home after 8 days in NICU on various meds and proceeded to give my husband and I the ride of our lives. He NEVER slept, cried constantly and we were told it was a combination of colic and severe reflux. The next 2 months were a complete blur and to top it off his neonatologist couldn't tell us to what extent Thomas would experience any developmental delays. Apparently he was oxegyn, nutrient deprived in utero due to a failed placenta and stopped moving. So for the next year we held our breath but he reached every milestone and some earlier than normal. Now that he is two he is talking, counting to 30, speaking Sanish as well as English and just a bright and articulate toddler. My son is an example of a miracle baby and I know how difficult having a preemie can be with all the "unknowns", but is does get better.
That is a very reassuring story for all parents of preemies! I think the difference between parents of premiees and the ones with full term babies is that the former get a reality check right from the start: your life is changed and you do not control it. Your kids might have serious problems and there is nothing you can do but wait!
