Myopia generally comes from an eye that is too long, since the eye lengthens as the child grows myopia increases.
Certainly there are always exceptions to every rule. You may certainly hope the myopia.
You child does no have 3 diopters of myopia:
1. The ped ophthal "over-corrected" him intentionally.
2. The astigmatism neutralizes some of the myopia. Read about spherical equivalent. Your child's glasses spherical equavalent is about -1.75 in each eye.

I was googling and came across this information
"It is generally not necessary to correct myopia
of less than about 3 D in infants and toddlers. Myopia of as much
as 3 D in an infant will sometimes disappear by 2 years of age.18,19
Myopia may also decrease in a child born prematurely; 50 percent
reach emmetropia by age 7. Moreover, because infants interact for
the most part with things that are close to them, they do not need
clear distance vision."

If I understand this - Does it mean that myopia of -3.0 in infants and toddler disappear by 2 years of age? Is this data reliable. They have cited some journals
If this is true do I have some hopes for my son who has 3 diopter myopia to improve over time?

This RX indicates a moderate amount of myopia and astigmatism. Only the pediatric ophthalmologist can tell you the amount of over-correction. So this is not a true measure of his myopia.
As he gets older the astigmatism may get better or worse the myopia usually gets worse.
