8 week old, FF, gassy and smelly green poo - what do I do?

[Gingerbreadpixie]

My 8 week old is FF on Aptamil ready made and has been pretty much from birth. He's always been a little windy but is a very settled baby generally.

Last week he had a nappy absolutely full of stinky green poo following 24 hours of no poo at all. I was really worried but his next nappy was its normal mustardy, pesto-like texture.

But for the past few days he's been doing these smelly green poos again, accompanied by a lot of farting and straining. Last night as I was changing him it literally shot out of his bum and up the wall! This can't be normal can it?

Is he developing some kind of milk allergy? Who do I speak to, the health visitor or GP? I've actually only met my HV once but have a good relationship with GP. Who tends to be more knowledgable with baby's diet/digestion?

Am a FTM so really worried and clueless

If you think it could be cows milk protein intolerance, there is some good info on allergy uk.

This explains the difference between CMPI and lactose intolerance]]

Thank you. Looking at the first link it doesn't seem like an allergy actually.

Does anyone know if reflux can cause green poo??

I experienced copious, green, stringy, slimy poo with DS for months from about this age, half a dozen times a day, but it was never resolved. Years later, I do still wonder what caused it. HV didn't know, GP didn't know, post natal teacher didn't know! We weren't referred or recommended a course of action because he was otherwise completely fine with no distress or other symptoms, and it went away almost the day he started eating solids, at 6.5 months (steamed and baked veggies mostly).

Not because of cows milk in my diet (he was EBF), as he's been having porridge daily with half a pint of milk ever since, and he's fine. Does perfect poos. All very mysterious. I'm not sure that this is any help at all - it's just meant to try to reassure you that it might be nothing at all of any consequence!

Could be a bad batch of formula?

Are you being very thorough with cleaning and sterilising? Green poos can be a result of bacterial infection and in FF babies its can be caused by bugs in the formula. I would re-sterilise everything, double check the teats to make sure they're getting clean and make sure that you're adding the formula to boiling water - I can't remember what the recent guidelines on making up formula are but use the ones on the dept of health web-site rather than side of formula tin. Sorry to sound patronising if you're already doing this but I know that we all have a tendency to cut corners sometimes.

I'm feeding aptamil ready made. No powder at all. So it's sterile. I suffer from contamination OCD so sterilising not an issue. Well, it is but over-sterilising if anything.

I called the GP and they weren't concerned but he's so windy. Farting all the time. The green poo episodes are at least 12 hour apart so it's not like its pouring out if him. I'm a bit stumped.

Bragadocia - that is interesting. He does seem fine in himself. Poo is not mucousy. Just green, pasty and stinky. He spits up a bit with burping but I wouldn't describe it as "vomiting"
