I love Musicology!! Mary and the all the instructors are wonderful!!! We have been going for about a year now. We patiently wait for our class each week. The munchkins love it! Stimulation indeed! It so fun to watch their development in class. Munchkin started with just the ability to lie on the floor and smile, now he is laughing and dancing all over the place! We will keep enrolling until he grows out it! Not only did we find a a fun place to go we have made many friends along the way! I highly recommend!!!
