The most recent travel insurance policy I bought should cover this:
We may cover journey changes caused by the ill-health of someone important to you
A relevant person is a person whoβs important to you but isnβt named on your Certificate of Insurance and is one of the following.
- A member of your immediate family
- Your travel companion
- A person directly related to the primary purpose of your journey
As your daughter is "immediate family" but is not a member of your travel party, changes to your travel should be eligible to be covered. Of course, the wording says "We may cover..." so it's still up to the policy provider's decision.
For your own travel insurance, a careful reading of the policy wording document should turn up something similar.
