Hindi masama, pero maraming moms dito nag-try ng dalawang approaches kaya let me share both! Some moms prefer na mag-fit perfectly ang christening outfit para sa nice photos at hindi awkward ang movements during the ceremony, while iba naman gusto ng konting laki para magamit ulit afterwards or in case may growth spurt. My take: kung gagamitin lang talaga for that one day, better to measure properly para comfortable ang baby at maganda ang pictures, pero kung gusto mo ring i-keep or ipamana, order a size up nalang para may room, okay lang naman slightly loose pa man, hindi naman napapansin ng guests!
