Five months old, and your baby uses rolling to chase what they want, sits with support, and clearly remembers familiar people and routines. Here is what is normal.
Typical day · week 20
- Feeds: 5 to 7 milk feeds in 24 hours
- Sleep: 14 to 15 hours across day and night
- Naps: 3 naps, wake windows of 2 to 2.5 hours
- Diapers: 5 to 6 wet per day
Feeding
Feeding is still milk-led, breast or bottle, with solids roughly four weeks away if you are starting at six months. Now is the time to watch for the readiness signs: sitting with support and steady head control, losing the tongue-thrust reflex, and real interest in food. Solids should never start before seventeen weeks, even with readiness signs.
Sleep
Sleep varies widely and that is normal. Separation protest may be growing, with loud objection when you leave the room, which signals secure attachment rather than a habit to discourage; responding consistently builds the trust that eventually eases it.
Diapers
Steady output, varying by baby and feeding type.
Growth
Your baby passes objects between hands, bangs them together deliberately, and drops things on purpose to watch and hear them fall, early cause-and-effect play. Support sitting with brief tripod-sit practice rather than long spells propped in a seat, which bypasses the core-strength work.
This week's leap
Clear memory of familiar people, places and routines, and growing curiosity about everything. Get outside often, grass, breeze and new sights and sounds all feed sensory development, and try not to compare your baby's timeline with others, since the normal range is wide.
From three months, 101.3°F (38.5°C) or above warrants assessment. No rolling by five months, or not bearing weight on the legs when held, can benefit from early physiotherapy. By five months your baby should turn consistently to sounds on both sides; raise any hearing doubt. If there is a family history of food allergy, discuss the plan before solids, as early, careful introduction of allergens like peanut now lowers allergy risk. None of this is medical advice; every baby is different, and your midwife, health visitor or doctor is the person to ask about your own child.
The calm way to follow all of this is to log it in one tap as it happens, then read the pattern over a few days rather than carrying it in your head. Little Bean shows this same week-by-week guidance inside the app, beside your own baby's log.
Quick answers: 20 weeks
How often should a 20-week-old eat?
Most babies this age take 5 to 7 milk feeds in 24 hours. Feed on demand rather than by the clock; steady weight gain and enough wet diapers are the real signs intake is fine.
How much sleep does a 20-week-old need?
Roughly 14 to 15 hours across day and night. 3 naps, wake windows of 2 to 2.5 hours. The range is wide, so treat these as averages rather than targets.
What are typical wake windows at 20 weeks?
3 naps, wake windows of 2 to 2.5 hours. An overtired baby fights sleep harder, so watch the clock and the tired signs together.
