Third baby so you'd think I'd be a bit more clued up by now but DD seems quite unsettled. She has about 5 ounces every 3/4 hours, we try burping her and keeping her upright but she only sometimes burps and often gets hiccups. She farts alot which seems to give her stomach pains and has become a bit constipated lately, I know little babies stomachs have to get used to working and all formulas have to have the same basic ingredients but I'm wondering if a different formula or bottle will help with the wind and constipation, we currently use MAM bottles and SMA little steps formula
