My 3 year old DD has very recently started becoming distressed when I leave her at preschool, to the point where they phoned me to collect her early today as she was so upset. She started in January and has always been happy to be left before this week but has cried for the last 4 days. There have been no major changes in her life, DH has had to go away with work a couple of times this year for 4/5 days but the last time was a few weeks ago and he shouldn't have to go again.
Has anyone else's child suddenly developed this anxiety and is there anything that helps them get over it or is it just a phase that will pass in time?
