Please tell me this 9 month sleep regression doesn't last long! My angel baby has gone from going down at night awake and straight off to sleep to crying/screaming etc sometimes on and off for an hour, I know she's ok cause I keep going in to soothe her etc and she smiles sometimes like she wants to play or get up. Hate hearing her cry, it all started last week when she got a cold and I had to obviously pick her out and comfort her. Now she's a lot better, she is crying to get up I think. I've tried all sorts, teething gel, medicine just incase it's her gums aching, but she's been fine today at nap times, any suggestions ladies?
