Being a great dad during your baby's first year (and beyond) takes patience and perseverance, but it's a heap of fun and one of the most rewarding things you'll ever do. Your child will love every minute you spend with her, whether you're changing her diapers when she's a baby, playing rough and tumble as a toddler, or teaching her how to ride a bike. Your time is by far the most valuable gift you can give your child.
