One of the best ways to help children learn to read is to read to them, a lot.
That alone won’t teach them to read, but it will help them a lot as they work through learning.
My kids have been “learning” to read since they were born and my oldest started reading on his own at age 4-5. I didn’t push him to read at all, he surprised me when he started telling me what the signs along the road said.
My younger hasn’t taken to it quite as fast but he’s right where he should be for his age, but we read at least three books to him every day at bedtime. I still read to my older one every day (we’ve read LotR twice), even though he’s plenty capable on his own.
