Isn't that why English is usually the near the top of language difficulty rankings? I mean, your point is true, but I don't know of anyone actually confused about it.

But for the real difficulty learning English, consider all the forms of "be" and the weird rules for which one to use. (Spanish is only dubiously better in this respect; there are still a lot of verb forms you just have to memorize, but at least you can follow actual rules on which form to use.)
This is in contrast to logographic symbol sets, that do not correspond to sound encodings. Think emoji.
Advanced grammar is a trap in all languages.
Hands down, teaching phonics is far and away the fastest route to being able to decode words. Similarly, reading to your kids is the fastest way to get them interested in reading. Using the motivation to learn to get going on the phonics is more than adequate to teach reading.
And don't expect things outside of spelling/reading to be any more "logical." Try explaining the rules of any sport in a way that isn't dominated by the exceptions.
