Hermione no need for baby bubble bath etc, they only need water for the first while. Although it's really cute to put them in a wee bubble bath, but seriously, I wouldn't bother.
Sugar you might want to think about taking a couple of nighties to hospital, one for labour and one for staying in, if ou should happen to be transferred to the ward. The labour one can get pretty manky. And make any hospital wear (nightie, slippers, jammies) dark coloured! One of the best bits of advice I was given, there's lots of blood about! Don't forget maxi-super-duper maternity towels too.
And also don't worry too much about toys, they don't pay much attention to them for the first six weeks/few months, so one or two is ok.
Queen of overbuying here, swore I wouldn't do it too much with this baby, already got far too much! Was a bit of a pain having to start again with boy clothes, I have so many beautiful girly babygros! I was obsessed with them, think I bought out next's entire stock every three months. Fortunately boys aren't quite so pretty, so mostly got basic ones this time. But, oh dear, I can't walk past a pair of dungarees without buying them, haha, I do love a baby in dungarees! Especially these and these!
