Do you know any Filipino folk songs that make good lullabies?

Tatlong Bibe mellow version haha! It's a hit for babies and adults alike nowadays. I wouldn't be surprised if kids can fall asleep with it as much as it can make babies dance joyfully while awake

I've used Bahay Kubo, Leron Leron Sinta and Paru-Parong Bukid as lullabies and it worked. You just have to sing it in a softer voice and slower tempo.

Bahay Kubo. LOL. It's our official and only lullaby for my five-month-old kiddo. Works all the time since Day 1

Ako ay may lobo and sitsiritsit are part of our lullaby medley aside from the ones mentioned by Sam above.
