I have a Bachelor of Teaching (Primary) that I completed quite a few years ago I don't remember finding it hard, but I didn't work or have kids then. Are you doing it off or on campus? Part or full time? If you are studying part time online/by distance it would be doable but you would have to be very disciplined in keeping up with readings/assignments etc. Do you have help/support for babysitting etc for when the workload gets heavy?
