You mentioned that he is given a lot of attention, so I would say, give him less. Children can be given too much attnetion, thereby they think they are the center of the world. Although there is such a thing as neglect, I”m not concerned with that and niether are you, I’m sure. But if my child were showing the signs you’re referring to, then I wold back off on the attnetion so he CAN develop the self-assurance and and security that comes from being by himself and knwoing that he isn’t the center. If he is used to feeling like he’s the center of your world (and by extenion, the rest of the world)m then when he doesn’t get his “drug” of attention, then yes he is going to fell insecure. So, you could say that a lot of attention CREATES an insecure child, just as neglect creats an insecure child.
I’d suggest reading John Rosemond’s materials and reduce the attention given to him; the adjustment will be tough, but better now than later.
He will begin to find ways to satisfy himself, thereby building confidence, instead of being dependent upon you or another adult. IMO, giving a child less attention – though reasonable attention that’s due a person and as circumstances requires – is one of the best things we can do for our children for them to develop resourcefulness, security adn self-confidence, not to mention imagination.
I hope this makes sense-I have a headache.
