I have a daughter and a son who were born 18 years apart from different mothers. My first marriage came at an early age. Before my first marriage was annulled, my daughter Alex and ex-wife were already living in California. I got to spend time with my daughter twice a year for a total of 30-40 days. When I visit, my entire agenda was her and nothing else. It was a hundred percent quality time.
Fast forward years later, I am blessed with another child from my second wife. This time, we are all living under the same roof. I get to spend hours of my day taking care of or playing with my son Axel. On weekends and holidays, we get to spend more time as we stay up longer. There are times we don't engage but we would be near each other. Thanks to technology, sometimes all three of us would be busy with our gadgets at the same instance. Axel would be playing wirelessly with my wife through the same game in their tablet.
Let's start with what's common between the two scenarios. I got to spend quality time with both of my children. Now comes the difference, the quantity. As much as I wanted to, I did not get to spend as much time with my daughter as I did with my son. I got to compare the results as well.
From one parent to another, our children grow up very fast. The quantity of time is as important (if not more) as the quality of time we spend with our children. The time we could have or should have spent with them cannot be recovered. Don't find the time, make the time. It's that important.
