Two DSs, one 4.2, the other 2.4 (ooh, palindromic ages, wonder if that'll happen again ).
Would like another one one day, but not sure about the going back to nappies/sleepless nights thing, plus would the little one feel left out when the big kids go off to do something they can't? Do you ideally need to have another one so the little one has someone nearer their own age?
