My almost three year old has always been fine being dropped off at nursery, when one of us leaves her and at bed time but it feels like over night she has suddenly started crying at everything-cries when I drop her at nursery, when me, dh or my mum leaves, and at bed time. I feel bad letting her cry herself to sleep at night but if I go in and give her a hug she just cries when I leave so I feel like I just prolong it. Please tell me it's a phase. There's been no upheaval or change in her life lately apart from getting a bed.
