Skills Gained This Month
The first social smile is the most anticipated moment of this month — not a reflex, but a real response to you. Your baby starts cooing. On their tummy they can lift their head to 45 degrees. They discover their hands and briefly track moving objects with their eyes.
Feeding
7-9 feeds a day, every 2.5-3.5 hours. The number of feeds drops because your baby takes more at each one. Cluster feeding in the evening — several short feeds close together — is normal and increases milk supply.
Sleep
Total sleep stays the same but the blocks start to lengthen; some babies give a 4-5 hour stretch at night. Three to five daytime naps is typical. The awake window is 1 to 1.5 hours.
Vaccines This Month
Around two months most schedules begin the primary series: diphtheria-tetanus-pertussis, polio, Hib, hepatitis B (often as one combined injection) and the first pneumococcal dose. Some countries, including Türkiye, also give BCG at this visit. Check your local schedule.
When To Call The Doctor
No eye contact at all or no response to sound at two months
Fever above 40 °C after vaccination, hours of inconsolable crying, or a seizure
Weight gain stalling, or a clear drop across percentile lines

When To Seek Care Immediately
Whatever your baby's age, seek medical care without waiting for: a fever of 38 °C or above in a baby under 3 months, a persistent fever above 39 °C at any age, laboured or rapid noisy breathing, blue lips or face, difficulty waking or marked lethargy, inconsolable persistent crying, complete refusal to feed, repeated projectile vomiting, bloody stools, fewer than 6 wet nappies a day, seizure-like movements, or the loss of a skill already gained. In these situations reach real medical care rather than an app or a web search.
