Hi, Bianca. Juan Tamad is always a classic. Kids also love Ang Pambihirang Buhok ni Raquel as the it has a lot of colourful illustrations. Ang Itim na Kuting also is a good one for it introduces kids about the idea of tolerance and acceptance.
This is a link to a site that suggest other books perfect for bedtime stories:
