Be sensitive: Following the birth of her first baby, the first question Buckley's husband asked when he came home after work was "Why is he crying?" The second question – "Did you feed him?"
What a father should do, she says – whether the baby is crying or not – is give mum a hug and tell her that she's wonderful.
Use your calming influence: – Get your shirt off, guys. Seriously! Lay the crying baby on your chest and allow it to listen to your heartbeat.
"We need to tell dads that they also have a heartbeat and if they place the baby on their bare chest and hold the baby for a few minutes it will reassure the infant."
Be supportive: Prepare a simple, nutritious lunch for the following day for the harried mum. This is particularly important if she's breast-feeding.
Be helpful: Stack the dishwasher, do the laundry or the hoovering.
"Often men simply don't understand why things are piling up – I found that when you point it out they can be brilliant to help," she says.
