In general, look for books na may colorful illustrations, funny stories, and simple texts. Ikaw pa rin naman ang magbabasa, so they'll just be happy looking at the images ☺️ 3yo ko loves his books, the key is variations. Kasi kahit favorite nya, after a month or even less, magsasawa na rin sya. Kaya ok lang din sa amin yung mga mumurahin sa shopee. Rotation na lang.
Also, if younger age, you might want to buy yung mga hindi madali mapunit ☺️
