It means less room in the house, but more love. I means more work, but more people to help you with it. It means there's always someone to play with. It means there's always someone to blame :). It means there is always someone to pick you up when you are down. It means more laughter. It means putting others before yourself. I means more people to love God. It means more people to share the gospel. It means more people to live for Him.
Being in a big family has changed me in more ways than I will ever fully know, but I wouldn't trade it for anything.
