I am fortunate to be able to work at home. The blessing is that I can see my family just about anytime I want to. The downside is sometimes family interrupts me while I am trying to work. But the other day I had an interruption that I was only too glad to receive. My youngest daughter, who is 8, came in and said "I just want a snuggle". Every once in a while she'll ask me to just give her a big hug. It's her way of knowing that she is loved. It would have been easy for me to tell her I was too busy or that I had other things I needed to do. But at that moment, there was nothing more important than just giving her a hug.
So often we become busy (and Dads especially have to fight against the pull of our jobs on our time) that we neglect the simple moments that God gives us to remind our children how much we love them. Take time to give your children a hug now and then. More importantly, make sure that they are getting to spend plenty of time with you. Before you know it, they'll be grown up and gone.
