DD is 7, and really enjoys school. She has a tendency to be clingy when I drop her off at breakfast club.
Since going back after half term, she has been really upset, crying and just wanting to be cuddled. She says it is because she misses me so much.
When she was like this in year 2, we both wore a pearl like stretchy bracelet, and when she missed me, she would hold one of the beads and this helped her to remember that I am always thinking of her.
However, she is now in year 3 at junior school, different headteacher, different rules. This morning we both put a little spot of my perfume on our wrists, and agreed that at drop off we would do kiss, hug, sniff! This did not work, and the TA had to peel DD off me 
Both DH and I have made sure we give DD lots of hugs, and she likes him to stay with her while she goes to sleep, which we don't mind as she obviously needs this extra comfort at the mo.
Have asked her if anything is bothering her at school. she says not. I will speak with the pastoral care staff tomorrow, but any suggestions of how else we can help DD are most welcome
