Query: Great!

I love this gym for my little one! He loves it now, and he's only 7 weeks old, and I'm sure it's going to grow with him. The animals that hang over the arc, he just loves to stare at, and the fact that they are detachable makes it easy to takes his favorites with us. The mirror slides around the arc too, so no matter where he wiggles to I can put the mirror to where he can see it.
