Query: A lifesaver!

My son, now 4 months old, was not at all interested in the cute mobile we bought to match his bedding - so my mother bought him this one. I was a little resistant - I liked the cute one - but my son LOVES the Sparkling Symphony mobile. Why is it a lifesaver? Because it's the one toy guaranteed to keep his attention (happily) long enough for me to take a shower every day!
