T.S.
I had a similar problem when my boys were smaller and as a pharmacist and herbalist I had to come up with a solution. The solution was a tea that helps with their digestion it is 2 tea bags chamomile tea, 1 slice ginger root, and 1/2 tsp fennel seeds to 4 cups water made into a tea and cooled. I would give it to them in a bottle and also made their formula with it. Works great for digestion. My sister in law who is breast feeding also uses the Gripe Water that I have sent her that helps in a similar way.
