What if my child is struggling to drink it?

If you child is struggling to drink the solution, you can try some of the following:

  • add the solution to a thick smoothie or yoghurt
  • put it in the fridge to cool down will help with the taste. You can also add ice cubes as well.
  • put it in a cup or bottle with a lid
  • give it to your child with a straw as this can help avoid it touching their taste buds

  • add to purred food such as mashed potato
