Some dads might like to have a little celebration with their friends and family after a new baby is born. Others might prefer a special dinner or date night with you while a family member or friend babysits for the night - as long as you're both comfortable leaving the baby alone, of course. It can also be a nice idea to just give them some time alone with the baby so they can get used to their new life or even let them take an extra long nap after a sleepless night. And of course, you can always celebrate him with a thoughtful gift too!
