My 3yrs old girl go to preschool. And she seldom drink water so cause her constipation. Any solution ?

Do inform her teacher so that they can help on this. When they are back home try to let them drink more water. Also fruits that start with P are usually good for easing constipation : papaya, plum, prune , pear Veggies like spinach and sweet potato are also good for constipation Have you given your gal yoghurt or probiotics before? It helps digestion too
