5.5 month old fishy breath?!

[user1499729649]

Hi everyone, I’ve just noticed today that my 5.5 month old’s breath has started to smell a bit fishy, her dummy smells of it too. She hasn’t started solids yet and only has formula milk. Has anyone else’s baby had this?! Thank you

Haven’t noticed this (my children are older now) but I think formula milk has omega oils added and they usually come from fish sources. I have sometimes done fishy burps myself after taking omega oil supplements.
