Is it within the "normal" range for DS (5 years old in YR) can't manage to count to 20 (struggles after 12) or to tell 6, 8, 9 after having worked on these numbers over and over?
He also struggles to remember the phonics sound for "d", letting alone weak on "b", "p" and etc.
He strangely has a thing, (not sure if playfully or genuinely confused), to write/COPY numbers facing the wrong way or from right to left for letters for a word. We started suspecting if he has dyslexia, but no other major signs though...
