Sleep Needs by Age
Wake Windows Are Key

Por Idade

Recém-nascido (0-3 meses): 14-17h/dia em períodos de 2-4h. 4-6 meses: 12-16h (início da consolidação noturna). 7-12 meses: 12-15h (2 sonecas + noite). 1-2 anos: 11-14h (1-2 sonecas). Bebês NÃO têm ritmo circadiano ao nascer — se desenvolve entre 6-16 semanas.

Janelas de Vigília

Tempo máximo acordado: RN: 45-60 min. 3 meses: 1,5-2h. 6 meses: 2-3h. 12 meses: 3-5h. Bebê hiperestimulado (acordado demais) é paradoxalmente MAIS difícil de fazer dormir.

⚡ CalcWolf Insight

The sleep regression at 4 months is not actually a regression — it is a permanent change in sleep architecture. Babies transition from newborn sleep cycles (2 stages) to adult-like cycles (4 stages). This causes more wake-ups between cycles. Sleep training after this point helps babies learn to self-soothe between cycles.
