Possibly she is a bit young to have milk and cheese as the gut needs to mature.
When symptoms occur you could start with a liitle diary of her intake and what come out (describing colour, frequency and consistency). Then when you suspect an intolerance start to cut out and keep making notes. When you’re still concerned I would seek advice from your Gp who can make referrals if needed

What was the outcome? I thought it was recommended to have no cows milk until after 12 months

very simple test at doctors now – don’t muck around, as it will get worse if it is an intollerance

How did you end up going? i am keen to know!!

Did you find out if she is lactose intolerant?

maybe trial and error. Remove the dairy and then after a day or two try her on one and see if you get the same result

how are things going now?

how did she go?

Did you find out what it was – I would have checked with the Doctor

Did you find out if she was?

How is she going now?

Did you end up avoiding both or just the cheese?

If you are at all worried, no harm in checking with you doctor.

Hopefully everything has righted itself by now.

How is she now?

It wouldn’t be anything she is getting through the breast milk is it?

What did you end up doing?

Wanted to know aswell, thanks for posting.

Try removing it from her diet if she is fine then maybe add a little bit back in and see what happens. Once you add it back in of see is unwell then you know she is

Hope you manage to find the answers and all goes well
