I had to find a new job after my previous employer sent a letter when I was on maternity leave telling me my job wouldn't be there for me afterwards - solicitors got me £2,500 which back then was enough to allow me to stay home until baby was 6 months. I know I was stressed going into a new job, 10am to 6pm 5 days a week, I think it played a big part in me not having more children; now ex-husband always earned less than me and wasn't helpful. My mum had him for 12 months, but wouldn't take him to play groups or nurseries, just home with her all day, no interaction with other children, which actually distressed me, my failure as a parent magnified ... But back to OP -
I was very tearful leaving baby, but eventually a routine was established. I was able to get a job locally and spent lunchtime at Mums with him, drop him at nursery/school. Worked there until he was 15! It was so difficult. But doable.
