This circle time song is supersimple for kids to catch on to, and when accompanied by felt letters, it's also a fun-sneaky way to help teach letter recognition, too. Just point to each letter as you sing it :)
M-O-M-M-Y (sing to the tune of B-I-N-G-O):
There's someone who I love the most
And Mommy is her name-o
and Mommy is her name-o
Warning: Be prepared to sing this song multiple times.
Adaptation: To avoid my own personal boredom (and to make things more nature-related), I insert animals into the song, and use pairs of little mom & baby animal felt critters ("there's someone turtle loves the most...") I put the mom critters on the feltboard, and hand out the babies to the kids so when they hear their animal called, they can match up the moms & babies on the board.
