I would encourage you to go with your gut feeling. We can have detailed arguments for and against each name but trusting your instincts is a really solid way to make a decision that you will feel good about in the future. It sounds like your instinct is leading you towards [name_f]Alexis[/name_f] [name_f]Marie[/name_f].
[name_f][/name_f]I would also add, nicknames are out of our control as our child gets older and takes ownership of their name, so I wouldn’t put too much weight on having lots of options. Combining sounds from the first name and middle name will naturally be more tenuous and may not have longevity as nicknames. There’s just too many unknowns to hinge the decision on this.
[name_f][/name_f]Lastly, instead of anticipating possible regret, another way to look at it is this: There will always be names we love but can’t use. We can love those names even if we don’t use them. It can help to frame those names as: not the right timing or not right for this particular baby.
[name_f][/name_f]Congratulations on your daughter’s arrival! All the best with your decision.
