Why not apply to only safeties?

It is fine to apply to a reach school. I would limit the amount of reaches to say one academic reach and one financial reach. Tell your child that making decisions is a part of life and that you should be able to narrow your choice down by making these tough decisions. Stress to the child that these are “reaches” and to not get hopes up. The odds are it will not work out so make sure they are ready for that.
