Girls, are all kids our age sleeping well lately?

Girls, are all kids our age sleeping well lately? We're 4.5 years old. Lately, sleep has become awful. He's been looking for me all night, or rather, his chest only wants to sleep with me. He used to sleep until 6-7 AM in the crib alone once fed at night and picked him up in the morning. But now it's terrible. He picks up toys, then throws them back, I don't know what to do anymore. It's like he's a robot lying still, not moving? and with his open chest! He can just give one little kiss and fall asleep, and I don't even know how many times?
