About two weeks ago, I noticed our son's attitude souring a bit. He tended to get irritated by anything and everything. I then asked him to do a stool check and could tell things may be starting to go awry with his stomach. (no blood, just runny) We're not sure what set him off, but he certainly seemed to be off. When he started preferring his Elecare over the food on his plate, we knew that it was time to go 100% EN for a few days.
It's been about 6 months since he's had a flare up like this, and it took about 3-4 days of 100% EN to get things back in check. Since then, we've begun reintroducing foods he would normally eat one meal at a time - using a guide of adding foods at about 50% of his caloric intake on the first day and then 80-90% on the next days. We continue to supplement with about 16 ounces of Elecare per day for growth reasons as well as maintaining our son's exposure to and taste for Elecare.
