Decorating nursery

Hi ladies. my husband and I just started trying to conceive. we bought a crib, rocking chair with a glider ottoman, Avent baby bottles 6 four ounce and 6 nine ounce bottles we bought a diaper bag and some diapers. we also bought a blue black and white car seat and stroller travel system. what is the best way to decorate a nursery without knowing the babies gender. we are trying to be very prepared for when when we do get pregnant and for when we have a baby.
