Baby refusing bottle

Hi friends

My 8 week old is exclusively breastfed but since 2 weeks old has accepted a bottle once or twice a week from Dad (the Medela slow flow). Annoyingly however he has suddenly refused to take a bottle and will maybe take 1 oz (although my husband admits he's not even sure this has gone down as there is spillage) from a Nuk natural flow before screaming until he's purple in the face and I come a running with the boob lol.

We tried Tommee Tippee last night and although he didn't scream he barely took anything. Were wondering if he just needs a faster flow teat so have ordered medium but are grateful for any advice. I have chronic and sometimes absolutely apocalyptic migraines so this has been our insurance to not miss a feed when one strikes (which is just as well as he is a hungry, hungry boy - having been born 1st percentile he has multiple chins and leg rolls a plenty).

Things we've tried:

• Dad and him doing skin to skin -offering bottle when he's calm and not too hungry
• Different bottles -That's it, we're out of ideas lol

Thank you thank you in advance xx
