Possible regret

We struggled to choose a name for our 3 month old daughter from our short list. After we chose one which was my favourite initially I have struggled to call them by that name a little bit and I feel awkward when other people call them it. She’s already 3 months now so I’m not sure I’ll ever really be used to it. The name is a very common one so it’s not that it’s an unusual name and that’s causing me to feel awkward or anything so I’m starting to wondering if it’s because I’ve picked the wrong one. I have to say that while I always really liked the name (the name itself is not the issue as I do think it’s a lovely name and had always wanted to use it), now I don’t think she really suits the name all that well and perhaps one of the others will suit her better. I can’t work out whether how I am reacting to his name means that I want to call him something else. Do you think that that might be what’s happening and does anyone have experience of feeling this way? Thanks x
