Phonics is of very limited use for learning to spell English, because at least 3700 common words have some unpredictable letters in them (speak, seek, shriek ...blue, shoe, flew, through). - That's why learning to spell English 'correctly' takes at least 10 years, with roughly 1 in 2 pupils still having serious difficulties with spelling by then end of secondary school.
Learning to spell English is mainly a matter of what looks right, but the physical act of writing or typing the correct version repeatedly helps greatly with this. That's why the old method of 'look, say, cover, write, check' remains the main way of learning to spell English.
People with good visual memories (roughly 1 in 5), and u may well be one of them, manage to imprint the right look of words mainly through reading. They don't have to work at their spelling. The majority have to slog away at it.
With young children it's important not to overdo the correcting of logical spellings like 'mite, cood, frend, sed, wood', because it can put them off writing. And if they don't write, they won't learn to spell.
Getting the balance right can be tricky. Most children want to learn to spell 'correctly' before long. Greater awareness of what makes this difficult can help. The worst thing anyone can do is pretend that English spelling is phonically regular. For weak spellers, it's much better to blame their difficulties on the stupidity of English spelling, to stop them feeling really bad about their difficulties.
