I cannot wait until I can get my kids involved in audio (3 and 5 now). I wish I had been introduced at a young age instead of just starting now. Thinking back to that age though, my brother and I had a Sansui AM/FM eight-track combo player that unfolded, and had blue fabric covering the front speaker panels. Listened to "WAR" and "Superfly" on it.
Best of wishes to your family and hope you have many memorable listening sessions with them.
