I haven't even started my maternity leave yet(due in Sept)but am already having doubts about going back. I've been part time since returning after DS and I'm just not sure that my heart is in to go back after number 2 is born. I'm not due to go back until next Easter which I know is ages away, but wondered if anyone knows how much notice you have to give or how much maternity pay you have to pay back if you decide not to go back.
