I use this in our MOPS Moppets Classroom for 6-14m/o. It works great to give a positive and settling tone to the room. The Teachers can sing or humm along to the tunes and the babies enjoy it and we have not had to call one mom out of our MOPS meetings yet this year. It's even calming enough to playing while some are sleeping.
I have given the Praise Baby collection DVD's to all new mommies in my church (as well as my grandchildren). They have wonderful, happy visuals and the songs are familiar to most Christians. The tempo is set for quieting before bedtime or nap, or early morning "rises" and feedings. What a great way to introduce your baby to the messages in song that point them to the Lord.
