I am that child. My parents were very eager to make a great career. Today I suffer from the emotional neglect with some issues such as ADHD.
Being a father myself today, I do think kids can do with relatively little facetime. But the time that is devoted to them must be exclusive quality time that makes it clear you love them and that you are present. There are studies that have shown that if fathers take 30 minutes of exclusive attention for their kids every day, it has great benefits for the child‘s development.
