Ooh I love New York too, but usually buy clothes for myself whilst there, as there's so much more choice for us larger ladies (a whole floor in both Macy's and Bloomingdales!)
Was last there in Feb, and I have to recommend that if you have time you should def try and get to see either The Producers or Wicked (prequel to Wizard of Oz) on Broadway, or Beauty and the Beast (saw that a few yrs back, but think it's still playing). They are all absolutely FAB!
Sounds like you're doing really well on baby gifts. We have my best friend (she had her baby, Poppy Tinsel, this week) lending us her new moses basket, and my parents will prob buy us whatever bits we ask for for Christmas (and b'days, as I asked to 'hold my present over' this month), but am expecting to buy most other stuff ourselves. Another friend has offered us a little used cot (used for twins, but only when in the country, and they lived in Conneticut mostly), but we are condidering buying a load of matching nursery furniture, in which case we'd have to decline their kind offer.
Limited on the pressie's from siblings though, as DH is an only child, and my bro is too self absorbed to think of something useful for someone else!
Oh dear - bit of a long message this one, so better stop there!
