Night time EBM bottle feed HELP PLEASE!

[darcysmum]

I have recently started expressing so Dad can give the 10pm feed to our daughter. She takes the bottle very well but seems to finish it very quickly and is now not settling well afterwards (which wasn't a problem previously from breast). She's 3 weeks & weighs 3.3 (just over 7lbs), & is taking around 3.5 (120ml) in about 10-15 mins. That seems very quick doesn't it?!
She does seem to gulp it down & I think she's what they call a 'sucky' baby - but i'm using size 1 newborn teat (avent) - don't think there's one smaller?!
Any suggestions / advise gratefully recieved! Want to avoid using a dummy....

I found DD drained a bottle much quicker than when I BFed her - it is easier for a baby to drink from a bottle than a nipple, they have to work for the milk from a nipple. Is she properly winded after having the bottle? She might be taking in more air which is making her uncomfortable.

Was just going to say, could it be wind? Babies take in more air when drinking from a bottle and need to be really well winded.

If she does settle much better on the breast, you could always consider going back to bfing her at 10pm and if your dp/dh wants "daddy time" he could rock or otherwise settle her to sleep after the feed?
