Step three is to be kind to yourself and your partner. Raising a kid can be mentally and physically draining at times. Give your partner some alone time, and take some alone time for yourself if at all possible.
Step 1 is fantastic, but step 3 is going to be mission critical. There will be times where you will feel like you can’t take one second more of screaming, or later one more “what do ducks do?”. Give yourselves time to disengage from the children. They really don’t require much hard work, but they do require nearly constant attention when they are young.
We’re all making this up as we go buddy. You’ll have good days and bad days. Don’t beat yourself up too much about the bad ones. Love your children, and don’t be afraid to tell them when you make mistakes.
