Between 10-20% of new mums develop postnatal depression and new research suggests that one in ten dads could also suffer from the condition. James Paulson from Eastern Virginia Medical School reviewed 43 different studies involving 28,004 new parents about fathers' postnatal depression and came up with the 1 in 10 figure. The symptoms were most common in the first six months after a baby's birth and men were more likely to develop them if their partners developed them too. The upheaval caused by the arrival of a new baby and feelings of apprehension about fatherhood both contributed towards the development of depression. The children of depressed men were twice as likely to suffer from behavioural problems - including hyperactivity - as they grew older.
