It will come as no surprise that some new fathers will be anxious or highly stressed. However, most people believe only new mums suffer postnatal depression. This is not the case. The rate of depression for dads is less than that for mums but our best estimate is that about one in ten dads will be affected. If there is a birth somewhere in Australia every 1 minute 46 seconds, then every day about 80 dads are being added to the depressed category.
