Be a support system. Help your child research the schools. Check on academic requirements, facts about he program, cost, etc. Make sure that all of the applications have been filled out completely and sent in on time. Young players may find it very disrupting and difficult to handle.
Some coaches are notorious for daily calling, while others are extremely laid back.
No calls before then. Your child should be honest with coaches. The coach will appreciate your honesty. You need to decide what sacrifices, if any, you are willing and able to make. Don't pressure your child to go for a scholarship if it is not necessary.
