You play a vital role in ensuring that the arrangement works and that your child continues to grow and live a happy life. That's why it's important that you also spend time attending to your needs, be it physical, emotional, or mental. Eat healthily, get regular exercise, and from time to time, do the things you enjoy like watching movies or catching up with friends.
At the end of the day, it's your child's best interests that will matter most. If you're still finalizing your divorce or you're contemplating the best options, do not hesitate to consult with a family law lawyer.
