You are going to need to stand up to your DH.
The thing about babies is that there is no right way and - crucially - every baby is different. Also you will get A LOT of conflicting and even incorrect advice.
As the babies mother you will have a stronger bond, at first at least. (This is not sexism, this is biology - the baby will have spent 9 months as part of you!)
You will have instincts about what is right for your baby that may contradict what the last professional told you - but you may be right!
Breastfeeding is a case in point. After several generations raised on formula we have become an anti breastfeeding culture. Despite the breast-is-best campaign coming across loud and clear, a lot of the professionals you will meet will actually have had very little up to date breast feeding training and often give crap advice. (Our BFing rates are amongst the lowest in the world).
One of the most important thing about establishing BFing - and most aspects of bringing up a baby IMO - is not only to learn "how it works " upfront as to know where to go for decent suppprt and help if you need it.
Google BFing cafe or BFing group for your area and see if there is anything locally. Trained peer supporters will often be in a better position to help than many medical professionals as the specialise and their training is up to date.
Cosleeping is another one. You may get a HV who tells you that cosleeping is unsafe. Your DH may tell you he doesn't want to share a bed. But actually you may find it's you who are getting up w very time the baby cries and are just shattered. You may discover - as I did - that if your baby sleeps with you, you all get more sleep. You may then discover that the NHS guidance your HV is quoting is not based on mothers sleeping with their their babies following the safe sleep guidelines, it includes all sorts of unsafe practices like falling asleep on the sofa or cosleeping if you formula feed (not bashing formula feeding - the science says cosleeping is safer if you BF).
You will find professionals disagree on things lime cosleeping. Generally I've found the sleep specialist scientists recommend it though - a good evidence-based resource on infant sleep in general is www.isisonline.org.uk
My point is not that you should BY or cosleep. My point is that - through your own experience and research (mumsnet!) You may find that what you believe to be the best thing for your baby contradicts the "professional" advice you've had as not all professionals you come across agree on this stuff - and some are very out of date (GPs often the worst! They get about half an hour on BFing at uni and what they learnt is often out of date now!)
Your DH will need to learn to trust your instincts and opinion when it comes to the baby not overrule you.
(The solution tgat workee for us for the cosleeping one was a three sided cot that attaches to your bed. Amazing invention, gave me more sleep - priceless!)
