First post here -- my son (3 mo) may have milk protein intolerance.
Anyway, he never grew out of pooping with every feeding, and it's gotten pretty bad about a week ago. I finally realized that 3 months was too old to still be pooping with every feeding. Sometimes, esp at night, it feels like he needed to eat so that he can poop. So, a week ago he was up 3 times to eat (and poop), following a dream feeding (and pooping). So I had to change diaper at 9 PM, 12 AM, 3:30 AM, 5:30 AM, and he ate at 8 AM (and pooped).
At this point I began to suspect dairy and stopped eating it. I saw a big improvement right away.
I spoke to his pedi, and he said that 8-9 dirty diapers was not normal for his age and that it could be milk protein intolerance. He advised to go off dairy for two weeks, and then reintroduce and see what happens. Baby was always a frequent pooper, but I think I made it worse recently when I started drinking milk again.
In any case, he did not really have any symptons apart from frequent pooping. He's generally pretty happy and only fusses when he's tired. He spits up a lot but it's definitely not reflux and he's not bothered by it much. He did have greep poops that you guys mention, but I thought it was a normal variation in color (?). He does not have rashes.
It's a bummer because I love yogurt and it's a good source of protein, too. On the other hand, I'm already eating gluten free (I have gluten intolerance) and consuming very few processed foods, so it would be simply cutting out yogurt, cheese, and butter. It's not like I have to overhaul my whole diet, and I read labels all the time anyway.
The pooping situation continues to be much improved, yesterday last dirty diaper was at 1 PM, and he went for 14 hrs without pooping after that! I think it's contributing to him sleeping better at night.
Anyway, does this sound like MSPI to you? Should I ask my pedi to test him sooner? Also, how do I know that there's blood in the poop? I worry about the damage his intestines may have suffered while I was eating dairy. He's back to orange poops, so maybe the damage (if any) is pretty minimal?
