0–6 months: Breast milk or formula is sufficient

During the first six months, the baby generally only needs breast milk or formula – even on hot summer days. This provides enough fluid, nutrients, and energy.

Tip: Avoid sugary drinks, squash, and juice – these provide empty calories and can increase the risk of tooth decay.

6–10 months: Introduce water

When the baby starts eating solid food, the amount of milk decreases slightly, and it's time to introduce water.

  • Start with a sippy cup – let the child practice forming their lips around the spout.
  • Try different models with or without a drip guard.
  • Small amounts at a time make it easier to learn without spills.

Tip: Food also contributes to fluid intake. Purees often consist of 80–90% water, as does yoghurt.

From 10 months: Small cup or glass

When the child is approaching one year old, you can try a small cup or glass without a lid.

  • Pour a little liquid at a time.
  • Choose glasses that don't break easily.
  • Let the child practice regularly to build habit and independence.

How much fluid does the child need?

A healthy child often regulates their fluid intake themselves. As a guideline:

  • 1-year-old: approximately 1 litre of fluid per day, including food.
  • Fluid intake from food is important to consider – vegetables, fruit puree, porridge, and yoghurt contain a lot of water.

Tip: Look at the child's energy levels, mood, and nappy status – if the child is alert and urinating regularly, the fluid intake is usually sufficient.

Sugary drinks – when is it okay?

  • Juice and squash should be avoided daily but can be given occasionally as a treat.
  • Water is always the best thirst quencher.

Tip: Introduce the habit of drinking water early – it benefits teeth, appetite regulation, and health.

Pay attention to changes

  • Babies are more sensitive to dehydration than older children, especially during illness.
  • Contact healthcare if the child:
  • Drinks much more than usual but is still thirsty
  • Drinks less than usual and urinates little
  • Is lethargic or listless

Prompt action in case of dehydration can be crucial, so do not hesitate to contact healthcare.
