I think that would be a good idea if you stick to a month at a time or even a day at a time. I was struggling like you doing a nursery nurse course full time, working and with four children one under 4 years old. The first year was great and I really enjoyed it but into my second year everything was a bit too much trouble I wasnt really enjoying the course but I thought just stick it out, youve started it now. Plus the fact I had my mother and others members of my family saying that I couldnt do it so I had to prove them wrong lol.
Keep motivated you will be glad that you stuck it out when you have finished.
