bottles and steralisers...

I hope are confident about breastfeeding too Confidence is one of the most important aspects of successful breastfeeding.
There is generally a lot of things Dad's can do to bond with their baby, they could be the person bub bathes with, goes on walks with (especially if Dad is happy to wear a sling - very good bonding tool!) or helps to resettle them. Once solids are introduced Dad can play a very prominent role in feeding!

Yes, introducing a bottle early can confuse babies and can affect breastfeeding because babies use their mouths very differently when bottle feeding. With a teat, the milk is easily released into their mouth, whilst with breastfeeding the baby uses more muscles in their mouth/face to feed. Some babies then begin to prefer a bottle because it is easier for them to get the milk and breastfeeding is comprimised.
Whilst your milk supply is establishing (the newborn period, first 3 months) introducing EBM bottle feeds may interfere with your supply, so if you want to do this it may be best to wait until everything has settled down to try your hubby doing the occasional feed. Once or twice a week would probably be sufficient because introducing one bottle feed a day on an ongoing basis will affect your supply - resulting your body making a smaller amount of milk for that time of day.

It really depends on the mother as to what they find easiest, hand expressing or using a pump. I just couldn't get enough out hand expressing (bit of an art to it, a good midwife, lactation consultant / ABA counsellor can teach you). I found an electric pump to work best, but that was just me!

I really recommend getting your hands on a few of the Australian Breastfeeding Association booklets like An Introduction to Breastfeeding & Expressing and Storing Breastmilk as they have plenty of tips (and info about hand expressing too).
