For the past 4 nights my almost 2 year old has been resisting sleep. Normally goes 8/830-730 She goes happily up to bed as usual, but after stories are read she decides she wants to walk around the bedroom or play. She can climb out of her cot so that's not an option unfortunately. She takes off her sleeping bag. She wanders about, sings and gets very irate if told to go back to bed. Last night she was singing and talking to her doll after 11pm. Obviously this morning she did not want to get up. Tonight she is upstairs, DH is seeing to her and she's still wide awake. She's tired but just won't lie down. Does anyone have any advice or ideas?
