My 2 and half year old has slept through the night since she was 6 weeks old and in her cot in her own room. She is noe two and half and all of a sudden the last week she will wake in the night climb out her cot take all her clothes off and come in to our room. If put her back in cot she will sleep another three hours and repeat process till we give in and she will fall asleep in our bed. When i ask her why she just says for me not to leave her in her cot!! I have no idea why she is doing this and is it just a phase? She has just started nursery and we have new baby who is now twelve weeks. I dont know what to do as i only had an hours sleep last night between the two of them waking and i am shattered.
