Colic Calm was actually referred to us by a friend who had a really colicky baby...we then asked our peds and she mentioned that it was gripe water/gas drops so she was fine with us introducing it.
At first we were using it when he got really upset, but now we use it during bedtime and it's more preventative. We realized that once he got really upset it was harder to give it to him (it can really make a mess) and it would take a while (20-30 minutes) before he would calm down. Now, bedtime dosage and maybe once or twice during the night and he is calm and we all sleep better.
BUT, I think I will start lower his intake and watching to see if he is doing better. And if so, once our last $20 bottle is gone, we will move on.
Again, thanks everyone for your feedback.
