I am in love with this program! This is way beyond a music class. Mary's instruction provided a variety of stimulating activities to do with our little ones . Each activity was the perfect amount of time , keeping our babies happy and engaged. ( our class had infants as young as 6 weeks and mine was the oldest @ 4.5 months) I loved how she explained how each practice was triggering certain development in our babies brains - even better - I could actually SEE my baby react to the activities! I was watching him discover , explore and learn. I felt extremely connected with my son during our visit. Even when we got home, I felt like he and I were calm and content. I was also very impressed with the small class size, the sweet mamas that were in the group and how CLEAN it was! The only complaint I have is that this class is only 1 time a week! I would go every day if could.
