I'm also worried about changing my child's name. The same kanji for city, town, and village

My second daughter was born in January.
It's a different pronunciation, but there are cities, towns, and villages with exactly the same kanji in other prefectures, and I'm worried that it would be better to change the names.
It's only been a few months since she was born, and I saw on the internet that it was easy to pass through the family court.

I wanted to associate it with my eldest daughter's name,
It wasn't easy to decide, but my husband told me about this from around fall,
This time, it was my husband's recommended name reading.
(If anything, the name of the eldest daughter is my recommendation)

However, it wasn't easy to decide on the kanji, so I was thinking by looking at the first and last name judgments.
In terms of name and name judgment, the first character with a large number of strokes was better, even if the same meaning was the same, but the husband wanted to match them with the same kanji as the eldest daughter, so the current kanji was a candidate.

I thought of the second character as a more girly character, but even though the older child is a neutral kanji, I thought it would be a pity for the eldest daughter that only the younger child has girly kanji,
It's not Daikichi, but I decided it based on my first and last name judgement and my own preferences.
(I've also seen that bilateral symmetry seems to be good...)

Even so, it wasn't decided before delivery, and the decision was made after being born from several candidates, including the reading.
But my husband wants to report it quickly, so I'm putting it out already, right? OK, decided!
I put it out with a feeling like that, and I regret that I didn't think about it a little more even though there was still a due date.
Also, I've seen that it's not good to use the same kanji as family, and I'm worried about that too.

The name of the older child is not limited to the municipality, but it can be in various places, such as surnames, etc., but it's not a ligature, and I think it's a name with a very good meaning, so I don't care about it at all.
But the younger one feels like a guess letter...
Even so, it's shocking that there are cities, towns, and villages with the same kanji, and even surnames with the same pronunciation.
(At the time of notification, I knew there was a city, town, and village, but I wasn't really concerned)

but it seems like a pretty big city...
In the future, if children go to that area, go to the city, or make friends there at university, etc., they will probably be laughed at...
With that in mind, now, just by changing the kanji a little bit, you won't have to worry about that! I think...

However, what remains in the family register...

My husband has already reported it, so that's fine! ,
They get angry, and they don't seem to care.

To be honest, I also have a feeling that it's a common name now, in terms of how to pronounce it.
I wonder if it makes me think too much because it's my husband's recommendation...
I can't sleep at night either...
