cory - yes, of course you don't need baby changing facilities, but they do make life easier, and I can imagine for some, more reserved people, having somewhere private to change and feed their baby might make the difference between them getting out and about and never leaving the house. And the point I was actually making, which would be true if you are out for the whole day whatever the facilities, is that the longer you are out, the more changes (nappies, clothes) you need to take out, hence the giant bag.
I must say, I do find it rather mean-spirited when people say 'oh, we never had that in my day, don't know why people need it now'. It makes you sound rather bitter, to be honest, that shops, galleries etc have helped make life that bit easier for parents (of course, whilst hoping to make money from them, but these facilities are free for anyone to use), but you begrudge that.
My mum is always so impressed with things for parents now, and comments, in an 'isn't that great' way, how much better things are now.
And of course, parents with prams can benefit from the excellent changes that have been made, particularly to transport, due to years of lobbying from disability rights groups - there is now space on most buses, tubes and trains (certainly in London) for people to park their pram. Lifts in many more stations too. I don't know anyone who wouldn't get out of the way for a wheelchair user, mainly by getting off and waiting for the next train/bus, though in actual fact in nearly 4 years of using London transport with a child, I have only once seen a wheelchair user, and that was during the paralympics.
It would be nice if older parents, who weren't so lucky in this respect, could show a bit more generosity of spirit when commenting on these. After all, my mum didn't have an automatic washing machine - but she would think it stupid beyond belief to begrudge anyone theirs, merely because she didn't.
