Ok, last night it happened again!! It was bad

DD woke up screaming in her sleep at least 6 times... I was up every hour with her.
When she would scream and with no warning, I would pick her up and hold her and comfort her and within a minute she'd be back asleep again..... she was fine as soon as i picked her up. This isn't like my DD??!
Is it because she's still getting over her cold/cough? She's got a pretty bad cough from the cold she had and maybe that's upsetting her? I can't work it out
But I am fast asleep and all of a sudden she's screaming and crying out!!!!

Even just before while sleeping in her cot in her room she started crying so i went in and she was sleeping still and hadnt woken up.... what the?? Could this be wind causing this???

Are you SURE babies don't get nightmares?? LOL
