Too posh to push? No, that's what mothers do.

Ann Voskamp has some words of wisdom for Kate about motherhood:

a mother’s labor and delivery never ends, and you never stop having to remember to breathe.

Let’s just be upfront: This can be a hard thing.

I once had a two and a half year old who climbed up a forty foot ladder on the side of a building.

One December, we all spiked fevers and had a collective tummy upheaval within 10 minutes of each other and it lasted 3 days. The baby was 8 days old. It was 5 days before Christmas. The house temperature fell to 58F and I had to get a fire started when fever burned through the bones and I couldn’t stand up and the baby kept crying and there wasn’t a clean sheet left in the house. Mothers can cry without a sound.

I know, I know, Kate — they all said that you were too posh to push, but whoever said that, didn’t know that that is what mothers do: we push through exhaustion, we push through overwhelm, we push through dishes and laundry and all these feelings of unimportance, because we’re the ones who live the biggest and realest and profound idea: that suffering produces perseverance, perseverance produces character and character produces hope and hope does not disappoint.
