I"m the same with all of them. I do expect a fair bit more responsibility from DS1 though, being the eldest and all, but hes the type of kid where you don't need to be on his back all the time kwim? the girls are different, They need to be kept in line or otherwise they can get pretty slack at stuff - like every two days I make them do a quick tidy up of their room cause otherwise if I don't it will end up looking like a tip. Obviously DS2 is too little yet to worry about too much, just as it were for the older 3 when they were the same age, but telling them from the very start that xyz isn't OK, or we don't do this or that helps reinforce that for when they are older, as it is easier to get them used to family rules from the outset than try to do it when they are older and are pretty used to getting away with it kwim?
