There is some good evidence and new research indicating that cognitive behaviour therapy (CBT) can be very helpful for children who are struggling to sleep, constantly wake and need a lot of reassurance before bed time. Some of the treatment evidence suggests that one of the best strategies is to not immediately tend to a child who has woken up unexpectedly or who cries for assistance. The strategy would include giving the child more and more time to self soothe before intervening. Another strategy includes rewarding good bedtime behaviours and rewarding consistency in bedtime routine. These are amongst some of the cognitive behaviour therapy strategies. In one case study sample, children showed up to 50% improved sleep through CBT.
