I think sadly a lot of the (non)support varies from area to area. As with much of the NHS it is postcode lottery.
GJ, if you got a MW who was well up on the latest advice re. BF etc. then you will be fine. There are places you can go to for BF support, MN (!), Le Leche and the other one that my tired brain can't remember right now, but I didn't even know these places existed when I had DS1.
Heron, TBH it has been that long since DS1 was trained I can't even remember when he came out night nappies, but I don't remember specifically getting up to take him to the loo. I think we just watched his liquid intake after 6 o'clock, and made sure he had a wee before getting into bed.
