Toddler constipation

Constipation is one of the most common health problems for toddlers. Here is why it can happen and how you can help.


Constipation means your toddler is having difficulty having a poo. Constipation can be caused by a poor diet, fussy eating, insufficient fibre, dehydration or incorrectly prepared formula milk. Lack of exercise can also play a part.

Toddlers sometimes become constipated if they have difficulties with potty training. Often they can be reluctant to poo in the potty or toilet at first, or ignore the signs that they need to go.

Constipation can also occur if your child is feverish, underweight or overweight, or finds it painful to have a bowel movement, for example because they have an a small cut, also known as an anal fissure, near the anus. If you are concerned that this may be the case, contact your healthcare professional.


How can I tell if my toddler is constipated?

If your toddler is constipated they may go a long time between bowel movements, or struggle to go despite feeling the need. They may also strain and cry as they try to empty their bowel.

Your toddler's stools are likely to be hard and pellet-like, appearing as either separate, hard lumps or as a lumpy sausage shape. In some cases, soft or runny poo can also be a sign of constipation. If hard poo builds up and is not passed, runny poo can build up behind the blockage and eventually leak out.


How can I minimise the risk of my toddler getting constipated?

A varied, balanced diet that contains plenty of fruit and vegetables will help prevent constipation. Give your toddler plenty to drink, too. They need six to eight drinks every day, around 100-120ml each, but more during hot weather or after physical activity.

Water is the best drink between meals. You can give water or diluted fruit juices with meals. Try not to let your toddler drink too much milk. It can spoil their appetite for food and cause them to miss out on the nutrients they need.


How can I help ease constipation in my toddler?

  • Offer six to eight drinks a day, including one with every meal and snack.
  • Continue to offer regular meals, with a planned snack half way between meals.
  • Include both fruit and vegetables with lunch and the evening meal and always make time for breakfast, which should include some fruit or wholegrain cereal or bread.
  • Include a starchy or cereal-based food with each meal and occasionally try a wholegrain variety.
  • Eat with your toddler, especially if they are a picky eater, so that they learn by example and get a balanced diet.


You could try a reward system to encourage your child to use the potty or toilet, eat healthy foods and drink plenty of fluids. If you think your toddler has a problem with constipation, speak to your GP or health visitor for advice.
