I have started to take homeopathic remedies (I was a skeptic until I took a remedy for migraines - and it worked better than the prescription medicine)
Go to 1-800homeopathy.com. They have remedies for everything including babies on up to elderly people. Even pregnant or recovering from pregnancy. And even pets! Try them out! It's amazing and not expensive. It's also not medicine (it's like herbal) and non addicting. And you can take it with medicine.
It sounds like your baby has a lot of gas and colic which the homeopathy helps with! I know...I have irritable bowel syndrome and use a lot of the tummy products. Just take my advice and read up on it. It's worth it.
