guitars

I also have pretty small hands. It gets easier when you have the right thumb position (even for easy chords like D, to make chord changes faster) and build up some strength and dexterity (exercises in the link below).

This is really good read: https://guitaristnextdoor.com/how-to-play-guitar-with-small-hands/

It also goes into gear stuff (scale length, thin and narrow neck, low action, lighter string guage, etc). Don't know what you have, but I would definitely recommend starting with an electric instead of an acoustic, unless you really only want to play acoustic or don't want to pay for an electric. It's a lot easier if you don't have naturally strong hands imo

It's not mentioned in the article, and you're in early days, but when you get into bar chords I recommend "strength training" on the guitar. Trying to hold the Fm chord (on the first fret) as long as you can, several times, with rests in between. But of course be careful, don't hurt yourself
