my 5 year old is similar! she seems to be sad or crying soooo much more these days! crying from the littlest things that happen... from me saying no to something.. from the bed feeling uncomfortable.. from being hungry.. from bad dreams, from worrying about stuff.. from stuff she cant explain.. i was starting to think she had some kind of anxiety disorder because although she has always been quite sensitive she has never been this upset so much. maybe it is a hormonal developmental thing? also, once she is upset she cant seem to settle herself down and will cry about other small things as well, so i might sort out the original crying reason and there will then be 3 more other things to sort out as well, as if she is making things up on the spot! its very frustrating and i dont want her to be so sad all the time. i want her to be happy!
