It's worth it in the end to be able to hold a little human being in your arms! The first smile, the first crawl, it's just yummy! Don't be surprised if going out for the first few months feels like a military operation - you have no idea how your designer handbag just doesn't cut it! You've got to find space for bottles (if you're using them), nappies - tons of those!, wipes (essential and you can't have too many of these), a clean set of clothes, a dummy (or two if you decide to use them) etc etc!
BTW once the teeth start coming through, get down to Boots pronto and buy "Ashton and Pearsons Teething Powder". Think it's called that - it's a homeopathic teething powder that comes in individual wraps like drugs but OMG they are superb! Everybody I've recommended them to has never looked back!
