I have 3 DC, number 2 and 3 are DTs so having 3 (at that point at least) was not planned. So we already have a bigger car, bigger house, have kissed goodbye the idea of sensible priced holidays/days out/any thoughts of private schooling - which are some of the main reasons given for stopping at 2. And many people mentioned 'middle child syndrome'.
on this basis, once you have 3 is it a slippery slope to just keep going? DH and I are planning DC4 (and hoping its not another BOGOF offer!!) based on the above, don't want a 'middle child' and the big cost outlays have already been done etc.
anyone else feel once you've gone past 2 there are less reasons to stop going on to 4, 5, 6?
