Kim - if that is your eldest DD's only concern then thats a bit different. If you want another baby go for it! I really admire anyone who has a huge family (by choice), I know I wouldn't cope. Gotta ask, do you have someone to help with the cleaning? Do you have a roster for jobs? There were 4 kids in our family and mum never made us do anything around the house. I loved it back then but me and my sisters all struggle juggling the housework now.
