This is one of the most common questions in the summer months. There is no single "magic month" on its own; the decision is made based on the baby's general health, the hygiene and temperature of the water, and the available sun protection measures. Even so, we can draw up a practical framework.

General Recommendation

  • First 6 months: The pool and sea are not recommended. The skin is sensitive, heat regulation has not yet matured, and because sunscreen cannot be used yet, protection is difficult; the risk of infection is high.
  • After 6 months: Under suitable conditions, short sea/pool experiences can begin. It is important that vaccinations are up to date.

Sea or Pool?

A sea whose cleanliness is reliable is generally safer than crowded pools. Be careful in pools: chlorine can irritate sensitive skin and eyes; crowded, poorly maintained pools are a source of diarrhea, outer ear canal inflammation, and skin infections. In every case a swim diaper should be used, and on getting out the baby should be rinsed with clean water and the skin folds dried (leaving the baby in a wet swimsuit is an invitation to diaper rash and fungal infection).

Water Temperature and Duration

Water around 28–32°C is comfortable for a baby; seawater is often cooler than this, so the first dips should be kept short (5–10 minutes), and if the baby is shivering or the lips are turning blue, they should be taken out immediately.

Sun Protection — The Real Issue

  • Avoid direct sun between 10:00 and 16:00; use shade, an umbrella, or an awning
  • In babies under 6 months, protection is provided through clothing, shade, and a hat; sunscreen is not recommended
  • After 6 months: A baby-appropriate, mineral-based (zinc oxide) sunscreen with at least SPF 30–50; reapply after coming out of the water and every 2 hours
  • A wide-brimmed hat, UV-protective sunglasses, and clothing
  • If sunburn develops: cool compresses, plenty of fluids; for blistering or widespread burns, see a doctor

On hot days, frequent breastfeeding is sufficient for the baby's fluid balance in the first 6 months — no extra water is given; for details see our article on water for babies.
