Like many babies/mothers, I tried several formulas until I finally decided to pay a little extra and buy this formula for my son and I haven't looked back. All tummy issues - GONE. All fussines - GONE. He is 5 months now, but has been sleeping through the night for about 1.5 months now and I think it has a lot to do with his nourishment. Also, his stools became less smelly and they changed from green to a healthy yellow. My son is truly happy with this formula! I am so satisfied with this product and I like that the ingredients are organic. I will definitely be purchasing other products from this line once he starts solids.
