Any idea what could make a 3 month old bf baby have poo like cat diarrhoea?

[Picante]

A bit like brown concrete?

Not really diarrhoea as she's only done one of them per day over the last few days.

Does bf baby poo change over time or is it always supposed to be yellow/orange mustard seedy?

I can't visualize brown concrete or cat diarrhoea not being a cat person.
Do you mean solid like concrete or grainy? Can you describe it a bit more? Photos are always handy.

There is a biiiig range of normal when it comes to baby poo. If it was soft I wouldn't be concerned.

Yes it was soft... er... creamy beige/brown? MacDonald's chocolate milkshake?!? I.e. not that runny!

Very pale poos - like mainly whitey creamy beige with a very slight brownish tinge can be a reason to check with your doctor. Please don't google. Not a reason to panic just worth a chat.

Thanks. She's supposed to be having her jabs today so I will see if the nurse has any ideas or thinks it's worth seeing a doc about.
