"They can become very anxious, even to the point of crying hysterically when they do not see their parents in front of them. Anastasia Satriyo, M.Psi., a family psychologist, explains that children under three years old, or toddlers, are indeed very prone to anxiety and crying when left by someone they know."

"Toddler children (ages 1-3 years) cannot yet understand the concept of time 'later', 'in 5-10 minutes'. Their brains only comprehend the concept of 'now'. A toddler's brain is not yet able to understand and differentiate 'this is my farewell to be left forever' by someone who is very important and loved by the child," said Anas."

According to Anas, the brains of toddlers are still primarily developing in the limbic area, which is the area for emotional and motor development. Additionally, there is the area for the development of simple language, aided by visual images that are repeated multiple times. This can only be understood by toddlers.

"Lakukan lebih sering main petak umpet di lingkungan kamar atau dalam rumah yang aman dan terprediksi untuk anak toddler. Termasuk bermain melihat dan menyembunyikan benda yang ditutup kain atau taplak," ungkap Anas. "Play hide and seek more often in a safe and predictable environment for toddlers, such as in the room or at home. This includes playing with objects that are covered with cloth or tablecloth," said Anas.
