Had three MWs at mine over the course - first came at end of her shift, so then got another, then had the third arrive as I was pushing, so didn't meet her til after (can't remember anything about her).
I didn't like the first - she just wasn't interested, was a bit annoyed at being on call, initially very dismissive of my silly wanting a homebirth for first baby. BUT - despite this she gave me fantastic advice, knew what she was doing and I think what she got me to do was helpful to the whole labour.
Second MW was excellent - gentle, calm, on the ball, respectful, encouraging. Plus obviously knew a lot about what she was doing.
Neither MW forced checks or mentioned wanting to go to hospital, but then my preg/labour was very straightforward.
So - even though I didn't really like the first MW they both did good jobs and I'm quite happy to take the luck of the draw with the NHS on call rota again. DP is very well informed though, so I do feel any MW will be challenged and have to explain everything in detail, which helps me feel less worried.
But in same area I know of quite a few NHS homebirths, all with different MWs and haven't heard any negative stories about MW attitudes. Maybe its like birth - people like to tell you the negatives more than the good/okay stuff.
