My 12 month old, who usually sleeps through the night, has begun waking once or twice crying. After I pick her up for 5 minutes or so, during which she is very sleepy, I place her back in her cot, and after a little grizzle, she falls beck to sleep. We have been on holidays for a few weeks (and her sleep was not great), I'm wondering if the change in envirinment has affected her? She is usually a big eater but she has become quite fussy, maybe she is not eating enough? Maybe it is teething? Comfort? I'm just don't know. Does anyone have any ideas as to why her sleep is interrupted? Thanks!
