Do your toddlers get nightmares? This week my 18 month old has been waking up saying No No No! Don't know what to do about it except comfort her, which sometimes takes a while before she goes back to sleep.

Yes of course. Toodlers, babies and even adults can have nightmares. Comfort her and she needs reassurance that you are there. Hug and kiss her, hold her tight. Nothing else you can do. With all the love and assurance, she will fall back asleep.
