While poor sleep during pregnancy and after that is common, Canadian researchers suggested cognitive behavioural therapy for insomnia (CBTi), which can not only improve sleep patterns but also address postpartum depression. 

The team from the University of British Columbia Okanagan and Vancouver campus University of Calgary showed that CBTi, which can detect thoughts, behaviours, and sleep patterns that lead to insomnia, during pregnancy can significantly prevent the risk of postpartum depressive symptoms after a baby arrives.
