Fennel, ginger and chamomile are all proven to ease the symptoms of digestive problems and, not coincidentally, are the ingredients of
gripe water. All three are GRAS (generally regarded as safe), but this depends on the age of your child. If you are nursing, I suggest YOU consume the fennel tea to help ease your baby's symptoms.
If your baby is over three months old and you are not nursing you might consider making a homemade version of gripe water. Here is a link for a recipe on my blog:

If you decide to use fennel tea, be sure that the other ingredients or herbs in the tea are safe. I highly recommend simply buying organic fennel seeds and boiling in some water (you can add a couple of raisins to the boiling water to sweeten-- some babies don't like the taste). You can give a little to your baby on a small spoon or use a medicine dropper.
I hope this helps!
