Re: Karo syrup in every bottle?
First of all, she should not be using Karo every single bottle. That can be really hard on baby's digestive system! Secondly, bottle fed babies do not poop as often as breastfed babies and often people assume that means they are constipated when they may not be. I think typical is once a day or thereabouts and it will be firmer too, more like mashed potatoes (someone correct me if I'm wrong there...).
Sometimes it takes 3, 4, or 9 different formulas before you find the right one that works for your baby so I'd definitely suggest that she keep trying others out.
