Sudden very smelly poos

[RaeRaeMama]

I'm concerned about this and I wondered if any other mums might be able to help

I exclusively breastfeed my baby (no bottles) the last three times she has pooped they have absolutely stank. They look fairly normal, possibly a little darker.

Usually her poo just kind of smells like sweet milk

Do you have any idea what this could be? Should I be concerned?

She is 16 weeks and happy in herself, but she has been sleeping very poorly the last week, she has been up frequently in the night

Please help, I posted on a breastfeeding fb page and nobody gave me an answer, I asked a nurse whilst I was at the GP no help whatsoever, I've been on google and can't see anything.

Is she teething? This can make their poo smell bad (sort of acidic) due to the drool.

Agree that it could be teething. If you've started introducing any food, that can also alter the smell of their poo.

Another thing it might be is a small bug?
