Check before you buy

Mattress size match. A full-size crib sheet must fit a standard crib mattress and stay tight. Mini cribs, bassinets and play yards need sheets made for that exact product or size. A loose or ill-fitting sheet can come off a corner and become an entrapment or suffocation hazard.
Elastic and pocket depth. Look for elastic around the whole perimeter. The pocket should be deep enough for the mattress but not loose; full-size crib mattresses are limited to about 6 inches thick in the US. Elastic that only covers the corners lets the sheet ride up when a baby moves.
Bare crib under 12 months. Use only a fitted sheet. No bumpers, pillows, quilts, positioners or loose blankets until at least 12 months, following AAP safe-sleep guidance. Soft bedding is a leading factor in sleep-related infant deaths. Crib bumpers are banned from sale in the US.
Sleep sack sizing and warmth. Choose a sleep sack by the maker's weight and length range. Pick the fabric weight or TOG to suit the room temperature. Use a sleeveless or arms-out style once the baby can roll. A sack that is too large lets the baby slip down inside it, and overheating is a SIDS risk factor.
Fabric and washability. Choose cotton jersey, muslin or percale that has been pre-washed or tolerates hot washes. Have at least two or three sheets per crib. Crib sheets get changed often, and cheap knits pill or shrink until they no longer fit.

Questions

When can my child have a blanket or pillow?

Under the AAP's safe-sleep guidance, keep the crib bare until at least 12 months; many parents keep using a sleep sack well into the toddler years.

Do I need a mattress protector under the sheet?

It is optional. If you use one, choose a thin, fitted waterproof pad made for that mattress size and put the fitted sheet over it, so there are no loose layers.
