NewbornWeeks 0–4Feeding on demand, sleeping in short stretches and slowly settling into life together. These first weeks are mostly about rest, recovery and getting to know each other.View Newborn Guide →
1 MonthWeeks 4–7Slightly longer alert windows, steadier feeding and the very first hints of engagement. Many families are finding their feet after the first weeks.View 1 Month Guide →
2 MonthsWeeks 8–11First social smiles and coos make the tiring days a little sweeter. Many babies show stronger head control during tummy time.View 2 Months Guide →
3 MonthsWeeks 12–15More smiles, more sounds and busy little hands reaching for whatever is nearby. Many babies are more settled than in the early weeks.View 3 Months Guide →
4 MonthsWeeks 16–19Grabbing, mouthing and maybe the first rolls. Laughs and babbles arrive for many babies, and sleep can shift around this stage.View 4 Months Guide →
