Thank you for your query.
You have not mentioned the exact location of the swelling on the head of your daughter. Is the swelling increasing or it is of the same size since morning?
I suggest that you wait and watch the swelling. In case it increases in size or causes any problems then you need to show your daughter to a doctor as it is very difficult to give any guidance without having a look at the swelling. Insect bites
can be red and quite hard in the initial stages though not bony hard.
I hope I have answered your query to your satisfaction.
Wishing your daughter an early recovery.
