Sing a song

I sing to Nolan and Olivia every night before bed. It has been fun the last few night as now Nolan is singing along and Olivia requests songs. Every night Olivia requests he sing "ducks" and "bus". Nolan then sings along, especially with the wheels on the bus. Then Nolan requests some songs. He usually wants to sing "ducks" again, but he also requests his song, Baby Mine. We usually throw Twinkle twinkle, Jesus loves me, and ABC's in for good measure.
