What was Niall Horans First Word as a baby?

Well, honey, I wasn't there to witness Niall Horan's first Word as a baby, but if I had to take a wild guess, it was probably something riveting like "mama" or "dada." Babies tend to stick with the classics when it comes to their early vocabulary. But hey, who knows, maybe he surprised everyone and blurted out "craic" or "craichead" for all we know!
