we want 4 but have stopped at 2 for a few(maybe even 5 or so) yrs
there is 22 months between ds and dd. we have (asa family) struggled with haveing them and the whole parenting game.
ds was our "easy child" so thats probably why we went again so quickly.. but it doesnt suit us atm(obviously nothing we can do about it now) so we have decided to wait a while before trying for #3 and then we will decide about #4 later.
