My kiddos are 10 weeks old (6 weeks adjusted) and are exclusively formula-fed. They were on Similac Neosure for the first 7 1/2 weeks. They had awful tummy issues while on the neosure. They were constipated, very gassy, spit up often, and just generally uncomfortable. The ped told us to try enfamil gentlease or goostart soothe. We tried the soothe for about a week and my DS seemed to do ok on it, but my DD did not. Now we are trying the gentlease and they both seem to be ok but its still very hard to feed them (they need to be burped very often throughout just 4 oz and they often seem just generally irritable while eating) and they still seem to be in pain/discomfort with bowel movements.
Are these things just normal? Should I keep trying different formula or is this just something we need to live with for now? I find myself dreading feedings and the fussiness afterwards :
