Until about 2 weeks ago my 13month old dd was quite good at sleeping through the night. We hadn't mastered getting her to go to sleep without being rocked in the pram (yes, I know, a rod for my own back, but lets not go there), but she would always nod off and go into her cot. If she woke in the night she either self-settled, or would go back to sleep in a couple of minutes with reassurance.
However, for the last two weeks she wakes up soon after going in to her cot, and is incredibly hard to settle. I tried to calm her down yesterday and leave her to stand in her cot, but she cried so hard she threw up everywhere, which rather puts paid to the idea of leaving her to settle herself. However, if I put her on the bed (either the spare bed in her room or my bed) she goes straight to sleep, even if I wander out of the room. I know she is only 13months, but might it be time to take the side off her cot and put on a bed barrier? It seems to be the cot she is scared of. Does anyone have any suggestions?
