Breast & formula transition - diarrhoea - 3 week old - help!

My baby is 3 weeks old and this morning since 7am (it is now 10.30) has had 3 mushy, yellow, overflowing diarrhoea poops. Besides this he seems well in himself, is still feeding, good colour etc. I’m wondering if this has been caused by me trying to transition to formula from breast milk?
Since 2pm yesterday I have given him expressed breast milk as my boobs were very sore, before this I had done 4/5 feeds of formula. Is it because I’ve gone from one to the other and back again? And does anyone have any advice about how to transition without causing this. My health visitor wasn’t very helpful and didn’t say much about it. Thanks.

Chrissy, this is the wrong folder on mumsnet. You need to post in Breast and bottle feeding.

Having said that, the poos sound normal for a breastfed baby of three weeks.

You can also call any of the breastfeeding helplines.

If you are concerned about your baby's health, try the HV again.

But you wont get much in the Relationships folder so do repost smile

Hi @tiktok ! I realised after I posted it, don’t know how I ended up on the relationships folder and wasn’t sure how to delete! 🤦🏻‍♀️
Thank you though smile

I did a mixture of breast and bottle from 3-6 weeks(not transition just top ups) and I didn't notice any difference in the poos.
Could your lo possibly be eating too much?
I think the main concern with diareah would be dehydration which doesn't seem to be the case for you.
Definitely seek medical help if you become worried.

It's normal for tiny baby poo to be liquid and yellow - I'm not sure there's actually anything unusual about the poo you're describing. If anything it's more common for a baby to get constipated when moving onto formula from breast milk.

The only way to try and minimise the effect of a transition would really be to do it as slowly as possible, replacing one breastfeed with formula a day or similar. But it doesn't really sound like you have much to worry about if your baby is fine in themselves.
