What are you doing to help your LOs gain weight? At our four month check, DS was in the zero percentile for his weight. He has MSPI so he is on Alimentum. The pedi suggested putting a tsp of oatmeal per oz. in all his bottles and an extra half scoop of formula. I have been doing both of these but they don’t seem to be helping since he spits up half of what he eats. I have considered waking him up to do a feeding in the middle of the night but hate to mess with his sleep if I don’t have to. We have to switch him to Elecare in a month if he doesn’t gain any weight. I really want to avoid that if possible since its $50 a can and it smells even worse than the formula he is currently on. Any other suggestions?
