“So far, things were going great, but you arrived and it all started to go wrong.” This is the typical comment grandparents make when we go to pick up the children. Sometimes we interpret that the child behaves worse with their parents, but, as Dr. Montse Arellano, a neuropediatrician from the pediatric service at Hospital Universitari Mútua Terrassa, points out, in many cases the opposite is true: "It is with them that they feel much more secure”. Children spend a large part of the day striving to adapt to school, with other adults, with friends... And there – Arellano states – they tend to behave more reservedly because there are rules and less trust to express what they feel. In reality, a boy or girl letting loose in the presence of their parents and not others, she points out, is usually "a reflection of emotional security", given that they know they are in a trusted environment where they can show themselves as they are, even when they are tired or overwhelmed.
