OK, just to respond to your last post - there are regular threads on here about whether or not DPs should do a night feed, I don't think there's a simple answer to it and a lot depends on what kind of work he does, when you would expect him to feed, etc.
What I would say though is if your DP isn't going to do a night feed then there's not much point in expressing a bottle which you will then give the baby, IYSWIM, same with introducing formula - if these things aren't going to give you a break then little point in doing it.
Your DD sounds completely normal
. Where it might be worth introducing a bottle is at tea-time/early evening - could your DP do a bottle then which would give you one on one time with your DD?
I'm not on a soapbox here by any means and you should absolutely do what's right for you and your whole family - including DD - but if you are still going to be the person doing the majority of the feeds then bottle feeding isn't going to help you out, really.
And honestly? I don't believe your mates
. They can't both have miracle babies.
Massive hugs to you and bf does get massively easier after 6 weeks by the way...
