Have you listened to Caspar Babypants yet? The music is energetic, playful, and non-patronizing. There are awesome videos, and the guy even shares his lyrics and chords on his website. If your library doesn’t own his whole catalogue of children’s music albums already, I encourage you to remedy this oversight immediately.
This autumn I started playing Loud and Quiet with my toddlers and preschoolers. We all practice meowing loudly and quietly, and then I pull out my puppets and we loud/quiet whatever I have in my bag that day. It’s been a big hit both with and without the ukulele.
Loud and Quiet
[MEOW!] Loud cat loud cat loud cat. Loud cat loud cat loud.
[meow] Quiet cat quiet cat quiet cat. Quiet cat quiet cat now.
[RIBBIT!] Loud frog loud frog loud frog. Loud frog loud frog loud.
[ribbit] Quiet frog quiet frog quiet frog. Quiet frog quiet frog now.
P.S. Don’t know the song? When I’m braver I’ll try to record it. Meanwhile you can listen to a sample on cdbaby (track 10).
