We were recommended Dr Brown’s bottles for anti-colic by the midwives & health visitors.
If you’ve got a microwave just get one of the plastic sterilising thingies.
If you are in a hard water area, I have heard of those auto sterilising machines clogging up in a matter of weeks; where we live it’s very hard water & most people said to not bother with them.
Freezer bags for breast milk are a good idea.
Electric breast pump is probably a good idea too.
If your Wife’s nips start to get sore, you can get nipple shields (having a baby opens up a whole new, weird world) to use while feeding & these cover things that go in the bra to stop the bra rubbing them red raw. My Wife swore by both of these items, but she struggled with breast feeding.
EDIT – oh, and congratulations!! We are only 7 months in with our little girl. Time sure whizzes by!
