Yep my DS3 too! Loves to do the head sitting thing, as well as rolling all over the place. He also has a mattress on the floor , and we dismantled our bed(as that's where he sleeps at night) and it's now just a mattress on the floor. All 3 of mine have been restless sleepers but more so DS1&3 when they're going off to sleep. DS3 can wake through the night and does it all over again, sometimes sliding himself off the mattress to sleep on the floor I can tell you too, having your head sat on, with force, while you're asleep is quite a rude awakening!
