Baby Bassinet: How Long and When to Transition
The AAP recommends a bassinet for the first 6 months of life, placed in the parents' bedroom. Most babies outgrow a bassinet between 3 and 6 months, or around 9 kg (20 lbs). Always use a firm, flat mattress and keep the bassinet empty.
When Should I Start Using a Bassinet?
Use a bassinet from birth until about 3 to 6 months, or when baby reaches 9 kg (20 lbs) or starts rolling over. The AAP recommends: - Place the bassinet in your bedroom for at least 6 months - Use a firm, flat mattress with a fitted sheet - No loose blankets, pillows, or toys - Keep baby on their back - Never use the bassinet as a travel sleep space in a moving vehicle Most bassinets have a weight limit of 9 kg (20 lbs). Once baby can push up on hands and knees, it's time to move to a crib.
Is a Bassinet Safer Than a Crib for Newborns?
Both are safe if used correctly. The AAP notes: - A bassinet is more convenient for night feeds - A crib lasts longer (up to 3 years) - Bassinets are smaller and fit next to the bed - Cribs are larger and more durable What matters most is: - A firm, flat surface - No loose bedding - Back to sleep - Supervised sleep For newborns, a bassinet works well. By 6 months, transition to a crib. For safe sleep, use soft towels and clean wipes.
How Do I Choose a Bassinet?
Look for: - A firm, flat mattress - Breathable mesh sides - A stable base that won't tip - Wheels with locks - A fitted sheet - Weight limit of at least 9 kg (20 lbs) - JPMA or ASTM certification Avoid bassinets with: - Soft bedding or bumpers - Music or lights attached inside - Vibrations that move baby - Cosleeper attachments that aren't certified For more nursery essentials, visit Moni Happy's collection.
When Should I Transition From Bassinet to Crib?
Transition when: - Baby reaches 9 kg (20 lbs) - Baby starts rolling over - Baby can push up on hands and knees - Baby is 3 to 6 months old The AAP recommends transitioning no later than 6 months. Most babies move to a crib between 4 and 6 months. To make the transition easier: 1. Start naps in the crib first 2. Use the same sleep routine 3. Keep the room dark and quiet 4. Give it 1 to 2 weeks For crib essentials, stock up on diapers, wipes, and more.
Can My Baby Sleep in a Bassinet All Night?
Yes, as long as: - The bassinet meets safety standards - The mattress is firm and flat - The bassinet is empty - Baby is on their back The AAP recommends room-sharing (not bed-sharing) for at least 6 months. A bassinet placed next to the bed is ideal. Never bring baby into your own bed. If you're worried about night wakings, keep a towel and pull-up pants nearby.
Bottom line: Use a bassinet from birth to 3 to 6 months, or until baby reaches 9 kg (20 lbs). The AAP recommends room-sharing with a firm, flat mattress and no loose bedding. Transition to a crib by 6 months. Choose a bassinet with breathable mesh sides and a stable base.
