We started Tyler on the new formula (EleCare) yesterday morning.  I was worried because I had read from other people using it that it smells and tastes pretty bad.  I don't know what they were comparing it to, though, because I actually think it smells less strong than the Nutramigen, and Tyler didn't seem to mind the taste at all.  Maybe they were comparing it to regular formula.  The one potential down side to this formula may be that since it is so highly processed, it is not as satisfying, since Tyler seems to be getting hungry more quickly than before.  Last night he had a bottle at 6, then we gave him another 3 ounces before bed at 8.  At 1 am he was up and was frantically hungry.  I fed him, and at 4:30 am he was up again, and again frantically hungry.  I am not liking this trend -- we had just gotten to a point in the last week or so where if Tyler had a bottle around 7 pm, a lot of nights he wouldn't get up again until 5 am!  That was beautiful!!  Now we may be back to one (or god help us, two) bottles per night.  Maybe last night was just a fluke.  Here's hoping....
