Why get kids started with music:
Parents and family who support and encourage kids to participate in musical programs and practice will often notice significant improvements in the child’s motor skills, not to mention an increased ability to concentrate, remember, and reason.

In fact, some studies have shown that any kind of musical training can actually increase the size of certain parts of the brain.

The ukulele is easy to learn compared to learning the piano, a guitar, or other stringed instruments. It has only four strings that help make it comfortable for kids to master the technique of finger placements.
They are small.

 13 Best Ukulele for kids 2022 | UkuleleWorld
 Rated the  Kala MK-SD Makala  Best overall
Kala Beginner Ukulele Review | PlayUkuleleNow 2017 article
Compared the Kala MK-S, KA-15S AND KA-S

Will a beginner be able to tell the difference in the sound quality of these ukes?
Probably not.

Construction:

These ukuleles are made out of a laminated wood, not solid wood. A laminate is a number of pieces of wood glued together, rather than a solid piece of wood.

Laminates tend to be stronger and less prone to splitting and cracking

Only the top of the MK-SD is wood. The sides and bottom are what Kala calls composite. A combination of ABS* like materials.

If the ukulele is made from solid wood rather than laminates it will have better volume, projection and tone.
However, many articles say that modern laminates are very good and a beginner will not notice the difference.

Some older reviews say the MK-SD top is agathis, but they now say it is Philippine Mahogany.
Agathis is a genus of 21 species of evergreen trees in the family of conifers (pines) that grow in the southern hemisphere and was common for guitars but has gone out of favor. It is often used in guitar manufacture. Like Mahogany, it can be good or bad, depending on how it is dried. If treated well, it makes an excellent tonewood for an instrument

Price:
Laminate Ukuleles: $25 to $180; Solid Top Ukuleles: $180 to $300; All Solid Wood Ukuleles: $300 to $800.

Strings: The New Nylgut Series of ukulele strings by Aquila were developed by blending three different synthetic components to make a composite material that sounds better and stays in tune better than standard nylon strings, but with the feel and playability of genuine gut.
An added feature of this exclusive composite material is that is was designed to absorb less moisture than other strings; which greatly improves intonation and tuning accuracy.
All these have Nylgut. Some old reviews said the SD had nylon.

Tuning Pegs: Tuning pegs are are pegs that go thru the peg box at the end of the neck. The strings are wrapped around these and are tightened or loosened by turning the pegs.
Friction tuners are a straight post. One turn of the knob equals one turn of the string post. There is a small screw in the end of the knob to adjust friction so it doesn't loosen when you let go.
Geared tuners use gear reduction so that somewhere around fourteen turns of the knob equals one turn around the string post. This makes for much more precision tuning.
All of these have geared tuning pegs which are easier to tune and more precise than the older friction pegs.

A common complaint about ukuleles is they don't hold tuning very well.
The most common cause is NEW strings stretching. This is perfectly normal and something you will have to deal with.
Just keep strumming and tuning and the strings will get broken in.
Pre-stretching (The process of tugging or twisting the strings) is controversial and not recommended.
There can also be problems with the peg adjustment or loose screws holding the gear to the peg box.

Frets:
The MK-S and the KA-15S have brass frets, the KA-SD has nickel frets, brass is softener than nickel, so the nickel frets will retain their shape longer.

Some initial comments I found.

Kayla KA-15S-ET Soprano
KA-15S 4.9 8 reviews $65
The Kala Learn to Play Starter Kit is a smart value for the aspiring ukulele student or self-starter. At its heart is a well-playing soprano ukulele built from industry-standard tonewoods: a rich mahogany body and neck and an articulate walnut fingerboard. An advanced nut and saddle by aftermarket guitar-parts leader GraphTech enhance this instrument's tone and sustain, while a set of Italian-made synthetic gut Aquila Supernylgut strings impart projection and tonal characteristics you'd never expect at this price


I went to Watermellon music in West Davis.
Their most popular version for kids is the kala makala MK-SD Amazon rating 4.6 45 reviews $61
A mahogany neck, and a rosewood fingerboard and custom bridge. It can be used for several applications by musicians and students in recording studios, rehearsals, for playing at home, and more.
The MK-SD/MBL has a powerful sound. The injection-molded body of the ukulele is built with 12 brass frets, and has geared tuners to ensure the instrument stays tuned. Aquila Super Nylgut. Featuring a custom dolphin bridge, this instrument looks great and is appropriate for the beginner or professional performer.
