Many critical illness policies do include some cover for your children – typically paying out if your child is diagnosed with a critical illness it covers or they spend over a certain amount of time in hospital.
If you make any claims for your child on your policy, it’ll generally stay active and you would be able to claim again if you were then diagnosed with a critical illness.
The amount of money you’ll get if your child becomes ill will generally be lower than your total cover, typically a proportion or set value. For example, 25% of the amount you're insured for or a flat £25,000.
