Parenthood has been the most challenging and fulfilling role I've ever undertaken.
Don't put all your eggs in one basket, especially one with so much risk.
Your son doesn't care about your work, your income, or the quantity of time.
It's the quality of time and the love given that will be remembered.
I've actually learned to appreciate a split schedule of custody as I'm a divorced parent as well. I get to miss my girls and when I have them it's all of their time. That was something previously taken for granted when I had them every day.
