I had a home birth and they helped me with the first and second feed. My MW then arranged for a breast feeding MW to come every 24hrs for the first 72 hrs. She also encouraged me to go to a breast feeding clinic 6 days later, which I ignored, got mastitis, gave up bf-ing for 18 hours and then finally went to a clinic. So great support but I wasn't in the right frame of mind to use the help!
The breast feeding people who came to my house were useless, but this was down to a postcode lottery. I have met the other MWs who serve the other parts of the city and they are fab. The Breast feeding consultants at the clinics and peer support groups I have attended were also fab.
After I went to the first clinic I made it my mission to go to every group available until we got bf-ing right! Luckily there is a group almost ever day.
Bf-ing didnt stop hurting until about 6-7wks. DS is now 12 weeks but we still go to one group a week for peer support.
I found out further down the line that I could call out a bf-ing MW to my house every day for the first 4 weeks and that we could also room-in at another hospital until we were happy with bf-ing. I didn't do this bit but I have met women who checked in for anywhere between 2-5 night and their partners could stay too. Unfortunately the hospital that offered the rooming in shut last month so don't know if you can do this at the main hospital.
I am in Cardiff by the way. Anyone who has a baby at UHW should ask for Judy who is head of breast feeding services in Cardiff. I have never met someone with so much enthusiasm and support for bf-ing.
My MW pointed out to me that I have now met every breast feeding counsellor/lactation consultant and MW in Cardiff

So to summarise a very long post
Cardiff has amazing support and help but you have to go to it.
