First weeks need to know?

Hi everyone!

Our baby girl is expected in three weeks and I’m starting to panic. Can any parent here share some advice from their first weeks as Mom and Dad. We have the mini crib, stroller and car seats, lots of diapers and diaper accessories. Our baby shower is this Saturday so we’re getting more gifts and needed essentials. This is our first so we don’t know what to expect. I’m very nervous about the lack of sleep we’re soon to experience.
