My 18 month old has suddenly started behaving scared at bed time, all is calm for the first part of the bedtime routine, she has her milk, story, lullaby, we put her in her sleeping bag, everything goes well until we put her in her cot, then she stands up instantly and cries, we cuddle and put her back down with reassuring words etc....... but it doesnt seem to help and last night it took an hour for her to get tired enough to give up, we gave her pain relief last night just incase she was teething, shes not afraid of her cot as she is fine at her afternoon nap, and we have an adequate night light which gives her room a nice glow,she has her fave toy that she loves, I am out of ideas as to what it is, does anyone else have any ideas?
