I'm sorry but I really can't stand this and have noticed it a bit on BH (the exercise picture thread springs to mind), as soon as anyone starts talking about working/ exercising/studying etc the snips about `well you must not spend much time with your kids' start. . It is OK to have things outside your kids and there is certainly a place for quality over quantity.
No argument here, particularly as I have been a working mother for the last 20 years! I was commenting on the balance as there seemed to be none.
