sounds pathetic I know and I am sure lots of SAHM's have no problem being with their children a lot. I have two children very close in age and one goes to kindergarten (germany) in the mornings and the other will go from August. So I will have the mornings for me to run errands, learn german and hopefully find some nice things to do.
However I sometimes dread the afternoons - the library is closed between 1-3pm and you are not allowed to use the playgrounds. Much as I do like living in germany - I am no hausfrau and every day from 12.30pm to 7pm when they go to be is quite oppressive at times. (DH very rarely home any earlier). I have at least another 1.5 yrs of this, maybe longer so I need for them and for me to get more pleasure out of it but on your own it can feel a relentless grind.
