I know maternity leave is a very personal thing but I need some sort of guideline as I have no idea what is an average time for people to stop work. I am a primary school teacher so my job is MASSIVELY active (ie: no time for feet up in the day or extended lunch breaks)and I'm due mid-June so likely to be quite hot. Last year temperatures in my classroom reached 35 degrees and I couldn't cope then. I am thinking about stopping work about 5 weeks before due date but really have no idea how big/ungainly we get around that time! Are there any other teachers out there who've done this before and can give some advice??
