When you're preparing for the birth of your child, the options can be overwhelming, especially if this is your first baby. Babies do need several things when they arrive, some of which are mandated by law and others that are purely for convenience. Focus on the essentials and add items as you become aware of your need for them as many products are of no use to you and, thus, only a waste of money.
Diapering and Clothing
For diapering supplies, you need to have enough diapers for about four dozen changes. If you're using cloth diapers, have about 10 waterproof covers in addition. If using disposable diapers, it's better to limit your purchase to one big pack of disposables as babies grow quickly and your newborn may outgrow the disposables before you've used them all. You don't need wipes at this stage, as your newborn's skin may be too delicate. Instead, have a dozen baby wash cloths that can be soaked in warm water available for diaper changes. Make sure to have a barrier cream (the most inexpensive is vaseline) if diaper rash develops. It's not necessary to have a full-blown changing station if you don't have the room or budget, but a changing pad makes any accidents easier to clean up. Get a diaper bag that both you and your spouse are willing to carry to make family trips easier, too.
For clothing, most pediatricians recommend one more layer than you have on to ensure your baby is warm enough. Buy six or eight side-tying undershirts (to avoid irritating the umbilical stump) for your baby to wear under her day clothes. Day clothes can consist of a couple of hats, two dressy outfits, five pairs of socks (booties can be included in this number), two pairs of mittens that prevent scratching (or look for shirts with fold-over ends), two jackets and a heavy snowsuit if your baby is born in winter (this is sometimes called "bunting"). Have three to five nightshirts available to wear under six to eight sleepers (look for sleep sacks to make night changes easier). Have on hand two or more blankets for additional warmth, or to block the sun if you're out in the stroller, and eight receiving blankets.
Feeding and Bath Time
If you're breastfeeding, keep on hand a breast pump, bottles and sterilized milk containers. You'll also need a nursing pillow to help your back and two nursing bras. If you're bottle feeding, have sterilized bottles, a bottle brush and sterilizer on hand. Make sure you have several types of formula as you won't know which formula works best until you've tried a few.
Bath time essentials include a basic tub (that you can insert into the bathtub, though you'll likely place it on the counter at first; check that it has suction cups on the bottom for safety), a dozen wash cloths (not the ones used for your baby's bottom), baby cleaning products and a soft hair brush to minimize cradle cap.
Legally Required
Most states have laws that require a newborn leave the hospital in a car seat, even if you don't own a car and don't plan to drive your baby anywhere. Check your state's legal requirements (many hospitals can also provide this information).
Convenience
As the first weeks wane, it's helpful to have some form of conveyance for your baby. Some mothers like a baby sling or front carrier; others prefer a stroller. In addition, it's helpful to have a play mat of some sort with toys that dangle above the baby's head so that you can give your baby a few minutes of play time without having to entertain. Rattles and other fuzzy toys (check for any choking hazards) are also helpful to have on hand.
If you're having your baby sleep with you, a co-sleeper that attaches to the bed is useful or a bassinet in the room with three sets of sheets is a good option. Otherwise, you need a crib and three sets of sheets at the ready.
If your baby soothes himself with extensive sucking, have a selection of pacifiers available. Nail clippers are also helpful to have on hand, as baby nails grow quickly and you don't want your baby to scratch his face.
