Warning! Poo Pics - is this normal?

[Hdp24]

Baby is drinking puramino formula due to severe cows milk intolerance. He has severe reflux and takes omeprazole too.
The last week he's had rosy cheeks and his poo is watery (diarrhoea) people have said he's teething (3months)
But, is his poo normal? He's content, has a little whinge trying to sleep, has his reflux spit ups... also had his vaccinations a week ago, so maybe that's impacted him? Any advice is welcomed.

Looks normal to me OP. I’ll caveat that and say mine are teenagers now but if he’s happy in general I’d assume all is well.

Another vote for normal here - it can become greenish when they are having tummy issues like what you’ve mentioned. Take LO to the drs if concerned but I don’t think it’s anything to worry about - poo changes all the time with little ones.
