Drop the expectations.
What’s best for your family is the same thing as what’s best for you. Put yourself first.
Try to taper off your workload.
Maybe, just maybe, consider NOT working up until the due date.
You are not a lesser woman or mother if you don't breastfeed.
Buy some liquid formula before your baby is born.
If you're planning to breastfeed, get yourself some nipple cream ahead of time.
Remember other people? Go see some.
If you can nip the competitive-parenting streak in the bud early in the game, you will be a happier woman for the rest of your life.
