Struggling teaching my almost 3 year old

I’ve been trying to teach my kid letters, counting, his name and age….

He has yet to grasp “my name is blank….I am 3 years old”

When I try to count he always says all the numbers out of order.

Letters are a lose.

Should I be looking into a specs h therapist? Early pre K program?

I can’t afford to pay and I don’t want him falling further behind. He don’t qualify for any programs. Currently looking for a new pediatrician. Our current one told me a load of crap regarding a medical condition he’s has and told me to put him in daycare( which I can’t afford)

UPDATE:

Thankyou. I was told by my pediatrician that he was delayed/lazy and should be doing all these things.
