Hello. Could you please advise how I can earn money while on maternity leave? I'm a teacher with experience. I would like to do tutoring, but now my baby is only 1.5 months old. As I am alone with him and we don't have a schedule yet, so this kind of work isn't suitable for now. Maybe there's something I could do during the day? For example, prepare any documents? Please advise. There's too much on my plate, I need to figure out how to find part-time work...
