Children can't be too attached; clinginess signals insecurity, not healthy bonding. The job is building security so kids feel safe exploring on their own, especially for sensitive children.
Chapters
There is no such thing as a child who is too attached. When a child is being clingy, that's not being too attached, that's insecurity. A child who's feeling secure in the moment doesn't cling. They want to venture forth and play. The tether gets longer because they know you're going to be there when they get back. It's important to know this, because if you don't understand what's really happening, you're probably going to make some bad decisions. As a parent, if you think of your child as clingy, you might push them away or get irritated with them, which only makes insecurity worse. If you understand that they're feeling anxious, you'll focus on helping them feel more secure, which is the only way to solve insecurity over time. Helping a child to feel secure can take time, especially if they're sensitive, but it's our main job as parents.
