Hi again
DS also goes to sleep quite early sometimes - I leave him there to sleep alone till I'm ready to go to bed. The room's babyproofed so it's safe for him to move around and we have a monitor so can hear when he's up anyway. Sometimes he wakes up again really quickly and we have to resettle him, but sometimes he's out for a few hours so I can have a little me time (or finish my work for the day ).
Really hope you can find a solution
