Started at birth Humana to give my daughter had but unfortunately many people's problems get the bowel movements and flatulence. So then I at Hipp Pre and then at Hipp am 1 landed. Now she is 7 months and I give her 2 Hipp so they sleep through slow times doing so she is tired more. So I have little success so far. But with Hipp 2 I'm still satisfied, it is well-tolerated, no flatulence, regular bowel movements and they also increases. We are very satisfied it and can recommend it, but every baby is different !!!
