When Can My Baby Sleep With a Blanket?

Your baby should not sleep with a loose blanket until 12 months old. The AAP says no loose bedding, pillows, or bumpers in the crib until your baby's first birthday; use a wearable blanket (sleep sack) instead.

When my son was born, my mom kept insisting he needed a blanket "or he'll be cold." The hospital nurse stopped us at the door. "No loose blankets," she said. "Use a sleep sack." It took me months to trust that a swaddle wouldn't leave him cold. Here's what I learned.

When Can My Baby Sleep With a Blanket Safely?

Wait until 12 months. The AAP's safe sleep guidelines say no loose blankets, quilts, or duvets before age 1, because they raise the risk of suffocation and SIDS.

The safe window: - 0 to 2 months: swaddle or sleep sack - 2 to 12 months: sleep sack, no loose blanket - 12+ months: a thin blanket is generally okay, but many parents keep using sleep sacks until 18 months My son rolled over at 5 months, so I stopped swaddling and switched to a sleep sack. The AAP says once a baby can roll, stop swaddling. For night changes, I keep diapers and wipes within arm's reach.

What Should Baby Sleep In Instead of a Blanket?

Use a wearable blanket (sleep sack). It keeps baby warm without covering the face, and it's the AAP-recommended option from birth to toddlerhood.

What worked for me: 1. A 0.5 TOG sleep sack for summer 2. A 1.0 TOG sleep sack for winter 3. Swaddles for the first 8 weeks, then sleep sacks 4. A fitted crib sheet only — no bumper pads, no pillows The AAP says room temperature should be 68 to 72 F (20 to 22 C). If baby's chest feels warm, they're fine. Cold hands and feet are normal. I use pull-up pants for quick overnight changes and keep tissues on the nightstand.

Is It Safe to Use a Baby Blanket in a Crib Earlier?

No. The AAP says loose bedding is a SIDS risk factor, and the risk is highest in the first 6 months. Even a "light" receiving blanket can cover a baby's face during sleep.

Why wait: - SIDS risk peaks at 2 to 4 months - Babies under 6 months can't reliably move a blanket off their face - Even " breathable" blankets are not recommended I kept a thin knitted blanket in the closet until his first birthday. On cold nights, I layered clothing (onesie + footed pajamas) instead. For more bedtime essentials, browse all products and towels for bath time.

When Is It OK to Introduce a Pillow and Blanket Together?

Most experts recommend waiting until 18 months to 2 years for a pillow, and 12 months for a thin blanket. The AAP says no pillows before 12 months at minimum.

Our transition: 1. 12 months: introduced a thin cotton blanket at nap time 2. 18 months: added a small flat pillow 3. 24 months: moved to a toddler bed Watch your baby's cues. If they're still in a crib, keep the sleep sack. If they're climbing out, it's time for a toddler bed. For the full bedtime routine, I pair sleep sacks with diapers and a bedtime book.
