5 Month Old Sleep Schedule: The Quiet Month Before the Next Shift

Why 5 months feels different from 4 and 6 months

If you've just come through the 4-month regression, five months can feel like a genuine breather — sleep cycles have matured, and your baby isn't yet facing the 3-to-2 nap transition that tends to land around 6 months. But "quieter" doesn't mean "nothing's changing."

Two things are specific to this month and directly affect sleep: rolling and, for many families, starting solids.

Sample 5 Month Old Sleep Schedule

Wake Windows at 5 Months

Typically 1.75–2.5 hours, starting shortest in the morning and lengthening toward bedtime. Overtiredness at this age shows up fast — as more night wakes and shorter naps — so if your baby is waking every hour, wake windows are one of the first things worth checking.

Rolling and the Swaddle Transition

Most babies begin rolling belly-to-back, and often back-to-belly, somewhere between 4 and 6 months. This is a genuine safe sleep milestone, not just a developmental note: once your baby shows signs of rolling either direction, swaddling should stop — a rolling baby in a swaddle can't free their arms to reposition themselves.

What this looks like in practice:

• Transition to a sleep sack or arms-free swaddle at the first sign of rolling — don't wait for it to happen consistently
• Expect a few disrupted nights during the transition itself; this is normal and usually temporary
• If your baby rolls onto their stomach during sleep and can roll back independently, current guidance is that you don't need to reposition them — but always place them on their back to start

Starting Solids and Sleep

Many families begin introducing solids somewhere in the 5–6 month window. A few things worth knowing:

• Starting solids does not reliably improve night sleep on its own — this is one of the most common myths parents encounter. Sleep consolidation is driven far more by sleep cycles maturing and consistent daytime rhythm than by a full belly.
• If you're night-weaning around this age, do it gradually and separately from the solids transition, rather than combining two big changes at once.
• Keep daytime feeds part of the wake window, not folded into the sleep routine itself, to avoid a feed-to-sleep association forming as solids ramp up.

Teething at 5 Months

This is often the age teething discomfort starts — even before any tooth is actually visible. Most babies begin teething somewhere in the 4–7 month window, with the first tooth typically erupting around 6 months on average, which means the gum irritation, drooling, and gnawing phase frequently shows up a few weeks before that first tooth breaks through.

What this can look like at night:

• New or increased night wakes that weren't there before
• Wanting more comfort at settling, even if nothing else about the routine has changed
• Excessive drooling, chewing on hands or toys, or general fussiness in the evening

A few things worth knowing:

• It's temporary. Once the tooth erupts (or the discomfort phase passes if it's still weeks away), sleep typically returns to baseline without needing a schedule overhaul.
• Avoid introducing new sleep props to get through it — rocking or feeding to sleep for a few teething nights can turn into a habit that outlasts the teething itself.
• Pain relief: a chilled (not frozen) teething ring or a clean, damp washcloth can help before bed. If your baby seems genuinely uncomfortable, a weight-appropriate dose of infant acetaminophen is generally considered safe — check with your GP or health visitor for dosing. Avoid teething gels, tablets, and amber necklaces, which current safety guidance advises against.
• Not every night wake at this age is teething. If disrupted sleep continues for more than a week or two with no other teething signs, it's worth looking at wake windows and sleep associations rather than assuming it's teeth.

Naps at 5 Months

Three naps is the target, with the first two typically the most restorative and the third a shorter catnap bridging to bedtime. Short 30-minute naps are still common at this age — many babies develop the ability to connect sleep cycles between 5 and 6 months. More detail here: Baby Only Napping 30 Minutes.
