Maternity leave?

How long are you planning on taking off? What are you doing to save money? I just added everything up and if I want to take 6 weeks we are going to need to save around $3500 just to cover bills. I'll be able to use my 2 weeks vacation time but that's it. I'm thinking maybe taking 4 weeks off then going back part time until 6 weeks, but then I'll have to worry about finding someone to watch our baby boy. Idk what to do.
