Affording Maternity Leave?!

Natalie
Hi Mommas,
So I'm only 17 weeks, but I'm trying to get a grasp on how to prepare for maternity leave. My fiancé and I both work about 30 hours a week (most the time) and it already seems like we're drowning in bills.. yay for adulting. We have a savings account set up to help out with bills while I'm on maternity leave, but are there any other tips/tricks to saving, budgeting, etc to prepare for that time with a new baby and no money?! Any help or advice would be very appreciated.
