I have 2 under 2. My best bit of advice: Try to be your best at all times. Work at 115% of your capacity. Do all the chores. All the diaper changes. Everything you can muster.
Because there will come a time where you or your wife will feel like somehow one of you is doing all the work. But if you commit to do as much as you possibly can, that rift can’t emerge.
I’ve found that taking care of 2 kids isn’t exactly the hard part. It’s maintaining a healthy, loving relationship with your partner that is the hardest. So keep that as the #1 or #2 priority.
