First rolls

Last reviewed · 3 min read · 11 sources · Plain-text version

Rolling usually starts around 3 to 4 months, tummy to back first. What changes for sleep when it does, why no raised surface is safe for a second, and a roll-over helper on the floor.

A white father lies on his side on a nursery rug in late-morning light, eye to eye with his thirteen-week-old who has just tipped from tummy onto their back, the mother laughing from the doorway.

A baby who can roll can leave the spot you put them in. Whether it's happened already or is weeks away, today is the day to plan for it.

Heart

Rolling usually starts around 3 to 4 months, sometimes earlier (Moon, AAP). Most babies roll tummy to back first, though the reverse is normal too, and many roll both ways by about 7 months (AAP). In a 1998 study, back sleepers rolled tummy to back a little later than stomach sleepers, still within the normal range (Davis et al., 1998). Back sleeping stays.

Head

What rolling changes at night. Always lay your baby down on their back, but once they can roll both ways, you don't need to keep turning them over; keep the crib bare, with no blankets, pillows, toys, or bumpers. Stop swaddling as soon as your baby looks like they're trying to roll, because rolling onto the stomach while swaddled raises the risk of suffocation, and never use weighted swaddles or sleep sacks (Moon, AAP).

Body

What rolling changes by day: there is no safe second on a raised surface. Rolling can start without warning, and babies this age don't fear edges (Dahl et al., 2013). On a changing table, never step away, even for a moment, even with the strap buckled (AAP). Among young children hospitalized for furniture falls in one study, a third fell from beds (Pomerantz et al., 2012). Car seats go on the floor: from 2003 to 2007, an estimated 43,562 babies were treated in US ERs for car seat injuries outside the car, mostly from falls (Parikh & Wilson, 2010).

Try today

  1. The father's hand resting on the baby's hip as the baby, on their back on the rug, twists toward a soft striped ball he has set down just out of reach to one side.

    Roll-over helper

    Time: 2 to 3 minutes during floor play · Roll-over helper in the guide

    1. With your baby on their back on a floor blanket, show a toy, then move it slowly to one side and down to the floor.

    2. If they turn toward it, gently guide their hips over so they end up on their side or tummy. Don't push; if they don't follow, it isn't time.

    3. Cheer, roll them gently back, and try the other side.

    Make it work:

    Only on the floor, never on a bed or sofa. In a study of 100 four-month-olds, those who spent more awake time on their tummies had reached more motor milestones, an association rather than proof (Dudek-Shriber & Zelazny, 2007); helping babies roll hasn't been studied on its own.

Watch for

  • Normal

    no rolling at all yet, or one way and not the other for a while.

    Talk with your pediatrician

    if your baby doesn't roll in either direction by 5 months (AAP).

  • Normal

    a baby who rolls onto their tummy in the crib after being laid on their back.

    Turn them back and ask your pediatrician

    if they can roll one way but not the other yet (Moon, AAP).

  • Normal

    a near miss that moves the changing pad to the floor for good.

    Call your pediatrician now

    for any head injury in a baby under 1 year, even if they seem fine, and call 911 for a seizure or a baby knocked out for more than a minute (AAP).

For you

The mother asleep on her side in her own bed in afternoon light, fully dressed, a glass of water on the nightstand, the bare bassinet beside the bed empty and the door ajar.

The sofa rule is for you too. Exhaustion is exactly when sleep drifts somewhere unsafe: sleeping with a baby on a couch or armchair raises the risk of sleep-related death up to 67 times, and bed sharing is 5 to 10 times riskier before 4 months (Moon, AAP). Plan for drowsy feeds instead: skip the couch and armchair, clear the bedding, set an alarm, and if you nod off, move your baby to their own sleep space as soon as you wake (Moon, AAP).

Your own bed, alone, for a real stretch, is the version of this rule that's a gift. Take it this afternoon if someone can hold the baby.

If you're the partner: redesign the 2 a.m. feed tonight. A chair with arms, low light, a phone alarm, the baby back in the bassinet.
