Delta Children Haven 4-in-1 Crib, $199.99; Target.com
Considering the safety implications of using a crib that's been compromised in any way, resist the temptation to use your old crib. Besides, since so many cribs now convert to beds, your older kiddo may still be using it! Go for this sleek, simple, reasonably priced model, which is available in three non-toxic color finishes and grows with you babe: You can adjust it to three different mattress height positions, and when the time comes, convert it to a toddler bed, a daybed, or a full-size bed.
Moonlight Slumber Little Dreamer Crib Mattress, $196; Ababy.com
Mattresses are also best bought new. Newborns need a firm sleeping surface. By now, the first mattress is not as firm as it was, and is probably...less than pristine, shall we say? This hypoallergenic buy has a clever design: One side is extra-firm, for infants, and the other is softer, for toddlers. The whole 5-inch-deep mattress is wrapped in a fire-, water-, stain-, and odor-proof fabric.
Chicco Keyfit 30 Infant Car Seat and Base, shown in Radius, $200, chiccoshop.com
You know the drill: a new baby, a new car seat. What we like about this Chicco model is that, thanks to a removable newborn insert, it will easily grow with your baby -- up until she's a 30-pound tot. A cushy seat lined with energy-absorbing foam helps make travel more comfortable, while a five-point harness system ensures it's safe. The company touts the Keyfit 30 as the "easiest car seat to install correctly." But for safety's sake, ask a pro to double-check your handiwork before you strap your baby in.
SkipHop Studio Select Day-to-Night Diaper Satchel, $90; skiphop.com
By this point, we're pretty sure you're over diaper bags that look like diaper bags, which is why this swanky-looking bag from SkipHop is a registry must. Sure, it has two insulated bottle pockets, a cushioned changing pad, and a water-resistant interior that can stand up to spills and crumbs. But it also has grown-up features, like perforated faux-leather details and metal hardware, so you'll be reaching for this fab bag long after baby's out of diapers.
JJ Cole Collections Changing Clutch, $19.95; jjcolecollections.com
Do you have to have two diaper-toting accessories? Of course not. But on those days when the thought of lugging around two kids and a full-on diaper bag is too much, you'll appreciate this clutch's small footprint (and snazzy print). Easy to hold, it unfolds to a 19" x 28" pad and holds several diapers and a wipes case.

Refresh your current stash with this pack of four oversize 44" x 44" wraps in too-cute animal prints.
BABYBjorn Soft Bib, from $14; target.com

The soft molded plastic a breeze to wipe clean, and a handy bottom pocket will keep stray Cheerios and peas from ending up on your floor.

BabyBjorn Baby Carrier One, shown in Khaki, $190; buybuybaby.com

After all, who else is going to pour the juice and squeeze out the craft glue? Here, the classic front carrier gets a modern twist with a padded waist belt and shoulder straps for extra comfort and support. Bonus: When the carrier gets dirty -- and trust us, it will -- simply toss it into the washing machine and it'll look good as new.
Bright Starts Bounce Bounce Baby, $60; kohls.com
If by any wild chance you still have your first activity center, by all means use it. But every mom we know counted the seconds until she could get this space-eater out of her house. If yours, too, ended up in a yard sale, pick up this smaller, more affordable version. Its seat spins, it bounces when your baby jumps, and it's tricked out with lots of cute features, like an alligator xylophone.
Vicks Baby Rectal Thermometer, $9.49; target.com

NoseFrida the Snotsucker, $15; fridababy.com
You may have skipped this handy tool the first time you were pregnant. Suctioning out boogers? Gross!

This time around, do yourself a favor and pick up the Snotsnucker. It's not cute, but it works and it's easy to clean.
