My DS has gone through various stages of this over the years, less so when he has less TV time in his life. My DS is essentially a very social creature, but at times I need to be firm with my boundaries and say no when he requests that I play with him to save my sanity. I usually offer for him to do his chosen activity near me instead. Sometimes we can strike a deal where I play with him for 15 minutes and then can go and pursue my own things. Otherwise I get him to read to me while I continue on with whatever it is that I am doing, which he loves. I think all kids probably go through stages where they feel the need to connect with others, especially their parents, to feel secure. Big change, leaps in development etc are often big triggers ime.
