DD2 is 22 months.She shares a room with her sister who is 2 years older, always has. Bedtime is drink, story, teeth, toilet, bed, goodnight,leave, both girls at same time. Last 3 months she has then spent the next 2 hours coming downstairs and being put back to bed. We are getting no evening. Tried sitting next to bed, other end of room, closing door (freaks DD1 out), letting her wander, ignoring her downstairs, putting DD1 in our room, DD2 in our room, Separate bedtimes. She isn't even teary,just stands and waits for acknowledgement, or comes and smiles at you.Tonight she kept coming half way downstairs, sitting with the cat and chatting to him until HE got fed up and batted her one. Trawled the net,anyone here got similar or advice?
