Are some babies just quieter???

My 9 month old baby is so sweet, and I’ve noticed she’s extremely observant. But like she can be very very quiet.

She’s extremely social, loves to laugh and smile, very smiley at everyone new she meets, and she does babble. She can say mama, dada, bababa, and Tata, but there are many days where she only babbles for a few times during the day or even the days she babbles a lot, like all through the day it doesn’t seem to be as much as her baby friend

Her baby friend literally babbles the entire day from the moment she wakes up till the moment she goes to bed. Mostly just saying “mamamama”. And here my girl can easily go a couple of hours and just say a little bit or even nothing at all.

It really scares me that something is wrong. Baby girl can follow a point, and just started waving and she is clapping a little. She laughs all the time and loves little games. Good at crawling and is pulling up to stand. I just wish she was more of a talker :(

Should I worry? Or is it just a personality
