My best source of advice was our doula. She was the one who opened our eyes to the possibility of choosing our hospital, and gave lots of suggestions based on what we said we were looking for.
The main advice I'd give is to go and have a look around for yourself (many hospitals run tours at set times) and get a gut feel for the facilities and staff. My most-local hospital doesn't do tours
, so that is a big reason for me choosing not to go there!
Otherwise, ask for opinions on Mumsnet and people you meet locally, and Google.
And remember, you can still switch quite late on in pregnancy, although it may mean repeat paperwork, blood tests and scans at the new place.
Last time around I didn't switch until around 30 weeks. This time I've had 12-week scan at the most-local hospital and am going back next week for the 20-week scan, but after that I'll switch. This was the advice of the midwives, as then you can make sure all is "well" before making your decision (in case you need special facilities for the baby). Also you can see if you're having a normal low-risk pregnancy or are likely to need special care.
Some of my midwives have got quite arsey with me about switching, but others are fine, so just be aware of that too.
