Two clinical psychologists have been appointed to help children in East Yorkshire who have been psychologically traumatised by the summer floods.
More than 100 schools were damaged by flooding in the region
Humber Mental Health Teaching NHS Trust said some children were suffering post-traumatic stress disorder after having to abandon their homes.
The trust said they needed rapid access to mental health treatment and the new recruits would help it to meet demand.
More than 10,000 properties were flooded in Hull alone on 25 June.
Clif Weston, consultant psychologist and head of specialism at the trust, said children might be affected in a number of different ways.
He said: "We will be treating children who may have post-traumatic stress disorder or phobias of some sort as a result of seeing their house flooded and having to leave their home and possessions in a hurry.
"Any family issues can be heightened at a time like this and there is also a risk of some children becoming depressed."
He said most children had coped well during the floods but a minority needed help.
"Parents may be feeling anxious and this anxiety can be transferred to the children.
"Appointing these psychologists will help us to meet the needs of children who have been psychologically traumatised by the floods and their aftermath.
"Having to leave your home is upsetting for anyone, but it can be worse for some children in the long term, once the sense of adventure and excitement has passed.
"We will be able to help them to come to terms with what's happened to them and, hopefully, prevent them from having longer term difficulties as a result of what they've been through."
