What to do if your child is unwell
It can be difficult to tell when a child is seriously ill, but the main thing is to trust your instincts. You know better than anyone else what your child is usually like, so you'll know when something is seriously wrong. If your child does not seem to be seriously ill, you can usually look after them at home. They should feel better in a few days. If they're uncomfortable, you can give them children's paracetamol or children's ibuprofen . Check the leaflet to make sure the medicine is suitable for your child and to see how much to give them. A pharmacist can give you advice about how to ease your child's symptoms and whether you need to see a doctor.
