Child Development, Vaccinations and Common Childhood Illnesses

The first years of a child’s life are filled with developmental milestones, routine healthcare contacts and the inevitable parade of childhood infections. This guide helps parents navigate the essentials with confidence.

The NHS Routine Vaccination Schedule

The UK has one of the most comprehensive childhood vaccination programmes in the world. Key schedule highlights: 8 weeks: 6-in-1 vaccine (diphtheria, tetanus, whooping cough, polio, Hib, hepatitis B), Men B, rotavirus. 12 weeks: 6-in-1 second dose, PCV (pneumococcal), rotavirus second dose. 16 weeks: 6-in-1 third dose, Men B second dose, PCV second dose. 1 year: MMR (measles, mumps, rubella), Men B booster, PCV booster, Hib/Men C. 2–10 years: Annual flu vaccine (nasal spray). 3 years 4 months: 4-in-1 pre-school booster, MMR second dose. 12–13 years (girls and boys): HPV vaccine. 14 years: 3-in-1 teenage booster, Men ACWY. Vaccines are available free on the NHS and represent the most effective public health intervention in history. Vaccine hesitancy remains a concern — parents with questions are encouraged to speak to their pharmacist or GP.

Normal Developmental Milestones (First Year)

1–2 months: social smile, follows faces and sounds, lifts head briefly when prone. 4 months: laughs and vocalises, holds head steadily, reaches for objects. 6 months: sits with support, transfers objects between hands, begins solid foods. 9 months: sits independently, pulls to stand, babbles “dada/mama.” 12 months: stands alone, may take first steps, 1–3 words with meaning. Developmental concerns should always be discussed with a health visitor or GP — early intervention makes a significant difference.

Common Childhood Infections and When to Worry

Chickenpox: typically mild, highly contagious, blistering rash. Treat with calamine lotion, antihistamines for itch. Give paracetamol if needed — not ibuprofen (theoretical risk of necrotising fasciitis in chickenpox is still debated but NHS advises avoiding). Hand, foot and mouth disease: viral, common in young children, small blisters on palms, soles and mouth. Self-limiting in 7–10 days. Roseola: high fever for 3–5 days, then fades as a pink rash appears. Benign. Croup: barking cough and stridor at night from laryngeal inflammation. Mild cases managed at home (steam bath, fresh air). Significant stridor at rest, or the child is distressed — seek medical attention.
