I'm no authoritah but the kittens knead their mommas to stimulate milk flow and the blanket sucking is like nursing their momma. I think they do the actions when they are older when they feel comfortable - usually just kneading though. The suckling might be due to being weaned too early but I can't back that up. Someone more in tune than myself should chime in.

My cat does this too. Can someone please explain the reasoning behind this?
