I'm 24 weeks pregnant and wondering when to start maternity leave. I work for a small organisation and would like to give as much notice as possible so my employer can find cover. My DS was born at 34 weeks so I took maternity leave suddenly and early with him so I have no idea. I have a sit down office job and it's about 30-45 mins drive each way M-F. I can't work from home. This is a very high risk pregnancy and I'm feeling tired/stressed already so don't want to work until due date. I could end up having the baby early anyway but just wondering what others did?
