My dd (aged 2) started nursery 3 weeks ago (2 mornings a week). She gets upset when dh leaves her but is apparently fine once he leaves. But shes become very clingy with us (me especially) and cries when people leave the room (even to go to the loo). At nighttime between 12-3 she screams and screams having just started to sleep through 2-3 nights a week. I'm genuinely worried she's been psychologically scarred by it. But we need her to start nursery as its getting harder and harder to justify only one of us working. Tell me this is normal and she'll be fine???
