This glow bug was his favorite toy when he got it from his Nanny. He loved it, and loved to play with it in his bed before going to sleep. Not so long ago he began throwing it out of his crib, and would cry, sometimes getting so worked up he would scream. We would go in and get it for him, wondering if it was for attention, or delaying the sleep process. For weeks we would go in and give him his glow bug, and for weeks he would throw it back out, and cry. FINALLY, we realized the music was making him sad, and he didn't want to hear it in his dark room before going to sleep. I figured it out when he would play with it during the day, out of his bed, and I actually watched him play the music, and get so sad and cry when certain songs would play. He just couldn't tell us, poor baby, we kept putting it back in his bed:( Another reason to help this boy find his voice!
