My LO was diagnosed with MSPI a little over 5 weeks ago. Since then, he has been on Nutramigen. He has done really well with this formula until about a week ago. I thought his fussiness was maybe due to a growth spurt (he doesn't hit them at the "right" times because he's a preemie) or because he dropped an overnight feed and I might be underfeeding him. However, he still seems a bit fussy and won't always finish his bottle. He's definitely not having the same reaction he had to my tainted milk or to regular formula though. No bloody or mucousy stools, no hives, some slight congestion but nothing major at all, no arching back and crying out in pain.
For those of you had to switch to Neocate because Nutramigen or Alimentum didn't work, was there a 5 week lag in issues?? What were their continuing issues? LO is still gaining weight well - he put on over a pound in the past 2 weeks.
Re: MSPI moms, come on in!
For us we noticed Alimentum wasn't working after about 2 weeks. For about a week or two LO did well, was less gassy and fussy. And then his gas started back up, he started spitting up more, the mucus in his stool increased, and he went back to being really fussy after eating. Our pedi said in our case it could have either been that LO was truly still reacting to something in the Alimentum, or that his digestive tract was just too irritated to tolerate the Alimentum and needed a less allergenic formula in order to heal. Either way, we switched to the Neocate and there was an immediate difference.
There were definitely never any weight issues with LO though - in fact he was always a really great gainer, his pedi thinks because he was eating constantly to try to soothe his stomach.
Good luck! Hopefully it isn't still an allergy, although on the plus side if you do have to switch to Neocate it at least smells MUCH better than Nutramigen/Alimentum .
