Mommies who applied for maternity leave, did you still file an application for the birth of a child and a monthly allowance? Or is all this done automatically immediately after childbirth? Just when I applied for maternity leave, the woman in the queue said that I wouldn't need to apply for anything else, but I'm not sure... Could you please share your experience?
