I gave HMF probiotic to my daughter until she was 1 and while she was on it she was a great pooper. Then I switched her out to something else because I got something g for free. After a few weeks she became constipated and did not **** for a couple of days. I tried everything prune purée, steamed pears, kiwis…nothing else was working. So I switched her back on to HMF probiotics and after a couple of days she was back to pooping 3-4 times a day. This stuff is amazing!
