When he is around 3 weeks, he had excessive gas and crying out with gas pains

I find that using a bottle warmer and making the formula warm reduces gas for my newborn.

Unfortunately it gave my baby terrible gas which made her first few days at home terrible

but I did for a few days and his gas was awful b/c of all the bubbles when I shook

I did not use the nipple top that came with the bottles as my son had terrible gas

but it gives her painful gas cramps.

Were not big fans of the nipple that comes with it as it can leak, so we resolve the issue by packing her Dr. Brown bottles and pouring it into there.

We use these formula to supplement during the first few days when my breastmilk is coming slow as well as when my husband helps me with one night time feeding

Great for newborn night feedings as well as for traveling.

One nipple per 4 bottles undermines the usefulness as an "on the go" solution, it's a slightly different color (weird yellowish/brown tint, the exact same brand made from powder is white), and even if I dump it into one of my daughter's bottles, she can tell the difference and doesn't like this.
