I agree with Bec - how ever many you want!
I take my hats off to all those Mums out there that have had/ want to have more than a couple of kids. It's SUCH a hard job (though the most rewarding!).
I honestly don't know if I could cope with more than 2... I think I'm too selfish.
Everyone's personality is different tho!
I have 3 younger sisters and I am sooooo glad that I have them. Being part of a big family can be such a wonderful experience - I have 3 best friends that I can count on for absolutely anything!
