My baby is almost a month old I was breastfeeding for 2 weeks and then for the past 2 weeks we've given her only Similac Pro Sensitive formula since the hospital started us off with Similac.. We just got WIC and they don't offer that kind of Formula instead they give Enfamil so we decided to switch to Enfamil gentlease since it's similar. I previously had signed up for samples from Enfamil and they recently sent me Enfamil neuro pro,Enfamil Inspire and Enfamil Gentleease. My question is would it be ok to try out the different samples to see which suits her best before deciding which one i want to get from WIC every month or would this upset her stomach? I just don't want to waste 3 perfectly good containers of formula if It's okay to use them. If it's of course not good for baby then I won't I don't want to upset her stomach. FTM BTW. I've noticed she's always a little gassy but it doesn't seem to bother her I've heard this is normal in younger babies.
