I found breastfeeding helped my bonding after a horrible experience the first time around. I ended up in a psychotic episode and my poor boy had to bear with it.
This wasn't because I was beating myself up about how I fed, because back then I had no idea of this concept that if you are told one thing is best, that the other thing is thus bad for your child. It was just an option there to take if I needed to, which I did, I mean I bought Huggies and then used Pampers, it wasn't much different. It was the illness after I gave birth that had a massive impact on my mental health. Being separated from my child was and awful experience, and I didn't have the natural skin contact that made it so much easier for me. Of course discovering parenting websites also made me find that there was this division between feeding methods, but that happened way after the fact.
My boy is a healthy little thing, formula was great, and it was necessary with being apart from him, then with all the medication that would cross into the milk.
With my girl it was simply that breastfeeding, slings and co-sleeping were the easier option, I had mobility issues, pregnancy worsened my physical disabilities, and I had a very fussy baby. The breastfeeding had a really handy side effect of combating the tendency to mental ill health thanks to those lovely hormones (which you still get cuddling them and formula feeding, this was simply easy and a big boost) and I also wanted to as my Auntie had just died of breast cancer and I knew BF helped to lower that risk.
I had the back up formula ready, I had bottles. I had been given lots of encouragement with the wanting to BF, but I never found it was divisive in the manner it was communicated. I think that may be staff allowing their personal opinions to cloud their professional duty. I know my midwife and HV wouldn't talk about brands of milk, but there was definitely plenty of support with bottles and sterilising and general how to.
If I felt a health professional was giving poor advice (which none is) with regards to feeding, I would talk to them, or another person on the staff about it, rather than walking away offended. I do get that being in a group means we are less likely to speak out, so maybe find her afterwards and ask why she can't give advice on bottles, that you felt you needed some information. If they are still refusing and they have no reason, then make a complaint.
It won't change without someone saying what about this, I need advice and support with this, and telling health professionals what we need. Right now I know they are encouraged to talk about BF support, because there was a lack and mum's were struggling, but that doesn't mean that you can't also ask for support for bottle feeding too, and if there is some sort of rule about not helping mums with bottle feeding, find out why and then stand up for your right to be supported too. If I were in your position, it's what I would do.
