Ok Mommas. I need advice. My husband of 14 years and I have 8 kiddos. Our oldest was a puker and I mean that literally. Every time he took a bottle he spit up or projectile vomited. Then we had six seemingly easy babies. Now, we have Nickolas. He spits up 75% of what he eats. He is 4 months old and is a 75% breastfed baby-- my supply has started to dwindle so we have had to resort to supplementing him with formula. What are some NATURAL things that I can do to ease his tummy. Please help. :(
