I understand the world we are in runs on money. We have to run, crawl, sweat for it. It is not easy to earn a respectable living considering the economy and price rise.
A newborn child or a growing child needs love as much as he needs a diaper, cereal, milk, or iPad. Growing up in a toxic family where parents are drunk, fighting will create havoc on his worldview. His growth will adversely be affected.
The money you will leave for him will worth nothing because he mentally undeveloped.
Your kid needs equal love, empathy, and family conditions for his growth. He needs mother and father to get mentored from, hear lullaby before he goes off for sleep. He needs his dad as a friend who will teach him how to ride, go fishing, hunting, or mend fences.
