Quitting full time job after maternity leave

Hi mummies, did you ever quit full time job on your first day work after maternity leave to be with your baby? This covid situation, my parents and parents in law unable come to SG due to travel restrictions. I also don’t think I can work at toxic environment any longer. The workloads require extremely long working hours. Had been thinking of quitting ever since my pregnancy but was convinced by my bosses to stay. Did you serve 1 month notice after maternity leave?
