My 7 month old girl has suddenly got so clingy its unreal. She wont even go to her dad. she will happily sit with me and intetact with people laughing smiling and babbling but the minute i put her down or they approach her she becomes heartbroken. She goes all stiff and sobs real tears. she stops as soon as i pick her up again. During they day at home ehen its just us she is the total opposite and wants to be left alone to play as long as im in the room. Is this just a phase, how can i help her.
