i could have written that post myself!!! My DD is 1 (in 2 days OMG!) and has been exactly like you have said for the last 3/4 weeks - it's like switch went off and she became a toddler!!! She has been teething and sick with a cold which hasn't helped, but in general she has just been really sooky and wanting cuddles all the time. What has helped i find is food (she is worse when she is hungry) and if she is crying because i have put her down to play and then walked away, i find that if i take the time to sit with her for a few minutes looking at her books or toys she soon gets sick of me and will go off and play on her own. If worse comes to worse, ABC2 for Kids goes on so i can at least do the dishes!!! she loves Thomas the tank (help me!!!) hahaha

Good Luck - remember it all passes (thats what gets me through!)
