This collection of 57 birthday wishes covers every kind of nephew, so you can find the one that actually sounds like something you would say.

Final Thoughts
A birthday wish for your nephew does not need to be long or elaborate to mean something. It just needs to feel like it came from you and like he is actually seen in it. Because that is what birthdays are really for, not the cake or the candles, but the reminder that the people around you actually notice who you are.
