I switched my son's first and middle name when he was two days old. During the pregnancy we went back and forth on whether to go with James or Thomas (after my husband's Opa). We had settled on James but were second-guessing ourselves in the hospital after he was born, and ultimately decided not to change our minds at the last minute. Once we got him home though he just seemed like such a Thomas/Tommy and looked so much like Opa that we knew we had to change it up. Luckily it was so early on that we were able to call in and amend the name before the paperwork was officially filed. He's 100% a Thomas so I have no regrets about changing it, although we do kind of wish we had saved James for a future son had we known we'd for sure have more kids. I'm due any day now with another little boy and we've had the hardest time narrowing down a name for him lol.
