Letting your kid learn how to have an independent phone conversation

My almost 8-year-old had his first phone call with a friend the other day where they were trying to exchange mailing addresses. Listening to the two of them try to relay information felt like listening to two 95-year-olds talking on half broken walkie talkies. But I resisted the urge to intervene and they eventually figured it out. Witnessing the moment and letting it unfold felt really special.
