Keeping things low key for your baby’s first Halloween? You get two looks for one withthis sweet set — perfect in case of an accidental blowout. The black bodysuit has an orange and white skeleton pattern on the front, with snaps at the legs and neck for easy on and off. The striped version features a sweet pumpkin-print design and tiny pumpkins on the covered feet, with snaps that go all the way up to the neck. Plus, these can be reworn throughout the season as cozy pajamas. Parents say the fabric is soft and high quality, and love that it comes in a preemie size. (Just note that the slightly different snap design makes the pumpkin version a bit easier to put on than the skeleton one.)

Looking for a spooky costume that’s more sweet than scary? You’ll love this adorable white bodysuit, which has a ghost face on the tummy and a matching hat with “Boo!” emblazoned on the brim. It’s designed like a standard romper, with long sleeves to cover baby’s sensitive skin and snaps along the inseam for simple diaper changes.
