Is there a phase at about 15 months when they're awake for 2-4 hrs in the night??

It's driving me mad! She does have a cold at the mo but even if she's dosed up, she's just awake and chatting / screaming out for us and we all end up awake for chunks in the night.

How long has it been going on? Could it be teeth? What time does she go to bed?

hope not as my son is a year old!!!

She goes to bed at 7pm and is out like a light and wakes between 6-7am for the day. It could be teeth but she doesn't seem in any pain, just bored and wants to play.

My DD used to do this until she was about 20 months. She used to wake up in her cot and sing and chat to herself for 2 hrs every night.
Even though she wasnt crying and she didnt appear to want us with her its still tough as I couldnt sleep knowing she was awake.

It did pass eventually.
