The three things I cant live without.
Gas Drops: Most of you will know what gas drops are. They help break down the big bubbles into smaller bubbles.
The Windi: Its what I call a " butt whistle". Its a little odd because you have to stick it in their butt, but it helps let the air out and also helps if they cant poo. Worth it! I boil them after each time I use them since its a little pricy to only use them once.
Gripe water: This help settle their tummies and Jax sleeps so much longer after having it.
If you have a colicky baby, I definitely recommend all three. (But of course, talk to your doctor first)
