Mental health is an area where people are embarrassed. They don't want to talk about it because somehow they feel they're a failure as a parent or, you know, they're embarrassed for their child or they want to protect their child, lots of very good reasons, but mental health, I feel, is something that you have to talk about.
If any of us caught a fever during pregnancy, we would seek advice and support from a doctor. Getting help with our mental health is no different - our children need us to look after ourselves and get the support we need.
