Little Plants / Plantitas 
This bilingual English/Spanish children's book uses plants to teach kids about feelings and emotions. It explains that plants can feel happy, sad, or  scared just like people, and emphasizes the importance of caring for both our feelings and our plants.
Ex. I feel happy like an orange sunflower, radiant with joy!
Ex. ¡Me siento feliz como un girasol naranja, radiante de alegría!
