Fibre & fluid for children

Fibre makes the poo softer and easier to pass. It comes from plant foods such as fruit, vegetables and grains.

Tips to help ensure you child has a good fibre intake


Don't give infants or young children wheat bran sprinkled over cereals or bran-rich cereals such as All‑Bran or San Bran. These may stop them absorbing important minerals such as iron and zinc. You can give 1 or 2 teaspoons of bran to children over 10, as long as they have plenty of fluids at the same time.

If your child is already eating a fibre-rich diet and drinking plenty of fluids, increasing fibre intake further and having extra drinks will not usually help constipation. In this case, they will usually need medications.
