I first put my son into nursery at 10 months, at first it was awful he cried everytime. Though he was always happy when I collected him so didn't worry. He stopped crying when I left him a while ago and it really relaxed me but in the last month he has become clingy again and now cries when I leave him. He was always clingy but the nursery changed him which was a relief but now its almost gone back 6 months. He is my first and is left 3 days he has one day with his Dad and the rest with me when I am around he wants me but is always happy with his Dad or both sets of parents. It really is so emotionally draining. Is this normal?
