9 month old and sudden yellow poo?

[Coffeecaketoday]

Hi all,

My 9 month old had a little sickness bug. She vomited a few times and then that stopped. Her poo then turned yellow and was quite runny for 1 BM, then back to normal consistency although still yellow. I assumed stomach bug. However it's been nearly a week now of these yellow poos, even though they aren't runny. She does seem a lot better today, no runny nose etc and less fussy so I'm hoping the poos will go back to normal? But I'm just wondering if this is likely to be a stomach bug or if I need to speak to the GP because it has continued? I know pale poos in adults isn't a good sign!

Thanks!

I should add she is forumla fed and has CMP allergy.

What has she been eating/drinking? Is she having mainly formula and not much food?

Yes I would say so, especially since she hasn't been well, that's all she would have. Although even with just forumla her poo has always been browny and never yellow. She is also teething so unsure if thast related.

Thank you for replying!

Oh I should add she is fine I'm herself! She's playing etc. although hasn't been sleeping well! But that's not new!
