When my daughter was about 4 months old she got colic although now they have all kinds of medications to cure this they didn’t back then they gave all kinds of ways to sooth but they were most affective for her. So I used the same thing that my mom has been using on me for years… Peppermint
Starlite peppermints You can use it in the form of star lite peppermint candy for small child you would want to melt it down in a man with water and then allow it to cool. works great!!
Mint tea Mint tea works great for people who are old enough to drink it.
You can also make you’re own tea with fresh mint leaves just boil them, And enjoy!!
