Query: Sunshine Symphony a lifesaver at times

Our daughter loved this even at a few weeks old. Now at 4+ mos., the novelty of it hasn't worn off a bit. Still on original batteries, too. I now hang it onto stroller or swing from linkadoo rings so it hangs out infront of her face while I'm cooking or working on other chores and it keeps her smiling and content. I've even held her on my lap with it hanging on exercise bike's handlebars so I can get some exercise and she loves it!
