Hi Emma,
Hope this isn't too personal...😱 ...but how are your erm, bosoms doing? I'm just wondering if it might be mastitis? Whatever it is, if you want to keep breast feeding just express, express, express! (If it is mastitis, this will help!) Even if you're worried about ketones in the milk & chuck it, at least it will help keep your milk flowing until you feel better...meanwhile if you're using a good teat on the bottle (we used Tommee Tippee "Closer to nature" bottles / teats!) then hopefully there shouldn't be an issue with getting baby back on the boobs once your happy to breastfeed directly again (whatever reason you're ill for!). We had to do top ups almost the whole time with M (good old Aptamil!) & he is a healthy feisty lad now, so don't let anyone worry you about top ups at any rate!
Hope that might help! In the meantime, really hope you feel better soon - don't delay going to the docs though, you've just had a c section & need to be looked after for a while so don't try & tough it out!! 🙂 Big Hug to you...
Hope you're on the mend,
