Glad to hear so many positive (but realistic) comments.
For me, going from 0 to 1 was a shock - lack of control, completely unprepared, took at least a year to get the hang of it, But now dd1 is 7.5 and wonderful, generally speaking.
Going from 1 to 2 was soooooo much easier, dd2 (now 4.5) just slotted straight into family life. Dd2 is quite a feisty little thing, but the two are great friends and really good company, although they aren't always angels, they definitely have their moments.
Number 3 is due in 10 days time, and we are all really excited. Not sure if this is sensible but I'm feeling quite calm about looking after a newborn again. After being obsessed with advice books and worrying what other people thought of my parenting skills (or lack of), I just feel much more prepared to do what I feel is right.
This pg is so much tougher though. No real health issues or concerns fortunately, but so much more draining, I think its because life is so much more demanding, although older children are more independent you end up getting involved in lots more - playgroup committees, school meetings, etc, etc than I did with smaller children, and so there are loads more demands on my time.
I have two concerns about number 3 arriving. Because we have two girls and we don't know what we are having this time, I can't bear the thought of someone asking if its another girl if we are disappointed. We love our two so much and treat them as individuals rather than as 'the girls' that whether this is a girl or a boy, it will be treated as an individual. And, I know it sounds like a cliche, but you do just want a healthy baby, I had a miscarriage last year, and believe me this has never been said more strongly.
The other one is that I don't want the older two to become little mums - they're only kids themselves, its fair enough that they fetch a clean nappy from time to time, but I hope I don't end up relying on them to provide entertainment (unless of course they really, really want to).
I've always wanted three kids - I hope my rosy image of life with 3 turns out to be just that
