WE moved our son out when he was almost exactly 2 - and no, he went to sleep as per normal & didn't get up and out at all - he could obviously get up in the mornings and then come through - but no ealier then he would have woken and shouted for us anyway ... that said, my ousin had a nightmare with his eldest boy just refusing to stay in the bed at night - so, like everything, it depends on the individual child. Trust your instincts and suck it and see!
