If you hope to get children one day, you should rehearse your conversations with them often. You can practice with a stone, they produce the same response.
Before I had kids, I swore to never shout at my kids. I visualized myself sitting them down for some little ‘adult’ talk about their undesirable behaviour. My speech would be smooth and chocolaty even. I was to be the calm and composed mother: the one who doesn’t lose her cool in the supermarket when they are screaming for candy and chocolate; then one who bends down to their kid’s eye level to avoid looking like an intimidating mammoth.
