Around ten and a half months, growing physical confidence meets a steadily expanding understanding of words. Here is what is normal.
Typical day · week 45
- Feeds: 3 to 4 milk feeds plus 3 meals
- Sleep: 13 to 14 hours across day and night
- Naps: 2 naps, wake windows of 3 to 4 hours
- Diapers: 4 to 6 wet per day
Feeding
Family foods with milk alongside. Offer simple choices, 'the red cup or the blue cup?', to give a sense of agency and reduce mealtime battles, keeping both options ones you are happy with. Variety still matters.
Sleep
One midday nap of one to two hours; predictable routines genuinely reassure and reduce upset.
Diapers
Stool reflects the diet; steady output is the marker.
Growth
Walking is starting for some and weeks away for others, both fine. Vocabulary is building, often a few words, with intentional pointing and requests, and comprehension well ahead of speech.
This week's leap
Imitation is now a main way of learning, so model what you want to see. Name feelings as they happen, 'you're frustrated because you can't reach it', which builds the foundation of self-regulation, and offer safe places to climb and tumble for all that energy.
From three months, 101.3°F (38.5°C) or above warrants assessment. No words and no communicative gestures, or not following simple instructions, by fifteen months is worth an early speech-and-language referral. If the intensity of this stage is wearing you down, support exists through groups and courses; parenting this age is genuinely hard. 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: 45 weeks
How often should a 45-week-old eat?
Most babies this age take 3 to 4 milk feeds plus 3 meals. 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 45-week-old need?
Roughly 13 to 14 hours across day and night. 2 naps, wake windows of 3 to 4 hours. The range is wide, so treat these as averages rather than targets.
What are typical wake windows at 45 weeks?
2 naps, wake windows of 3 to 4 hours. An overtired baby fights sleep harder, so watch the clock and the tired signs together.
