DS is 1 year next week, but he's really been struggling with settling in at nursery. So far, he's had about five sessions there, varying between 2 hours and 5 hours. Most of the time, he just screams the whole time. I try and call after 90 minutes to see how he's doing - he's still screaming.
Today was his first full day, I go back to work in two weeks. They've just called me saying he's not eaten or drunk anything all day. I ask if I should come and collect him, they say that's up to me. 
What do I do? The plan is to collect him at 5 but I could hear him screaming through the whole conversation.
