Family Share-Child's Apple ID password for all app store downloads?

Is there a way to set it so the child does not have to enter their Apple ID password for every app store download? I have it set to ask to buy so I am getting the notifications to approve or deny but on her device it's requiring her to enter her password three different times in the process...twice when she hits "get" before it brings up the option for her to send the ask request and then again when it's been approved before it'll start downloading. Why would she need to enter her password in this way? Is there a way to stop that from happening?
