I'm a primary school teacher and expecting DC2 next year. I have struggled to manage work and family life since having DC1 - I work 3 days a week, which was supposed to help but I had my child at home with me all the time on my days off til he went to school and I found it hard to get anything done in the house or for work. Then I would spent every evening and half the weekend working, I was putting 50+ hours into a p/t job.
I was spoken to with concerns about my performance before becoming pregnant. I can't see me becoming more effective with two children to look after 
Ideally I would like to change careers after DC2 arrives, but have no idea what else I can do. We can afford for me to take a drop in salary, but whatever I do would need to justify the cost of childcare for a school aged child and a baby. We don't qualify for very much CTC as DH earns close to 40K.
Any ideas? What do people who leave teaching actually do? I don't have much experience of anything else, apart from a bit of youth work.
I could possibly afford to retrain but would be worried about studying while teaching, think I might collapse under the strain of that!
