I tend to agree Emma. I managed a part time role quite easily when my DD was young. It was as a teacher's assistant thus a "leave the job when i leave the place" kinda role. If I had been a teacher it would have been trickier especially at weekends, juggling family time and time to plan/marking etc... although I know many teacher/mothers must be able to do it quite well. ETA: also agree with the "wonderwomen" who return to work when their babies aren't sleeping!
