As your experience illustrates this works well but it’s not necessary. Breaking down words into phonemes is not something people from illiterate cultures do normally. It’s not excessively difficult to teach by any means but it’s also not something that comes naturally as you’ve no doubt seen when teaching children how to sound out words when learning to read. Teaching consonant vowel consonant words (cat, rat, rag, bag, tag, tug, bug etc.) if you sound out a word phoneme by phoneme they’ll often get one wrong when they put it together, usually the vowel.
In the environment of evolutionary adaptedness language acquisition would not primarily occur in a nuclear family, children would spend a lot of time around not just their immediate family but also with other nursing mothers and children close in age and as they get older with children close on age more generally. They pick up pronunciation from the environment and all the other elements of a language too. This is why children will reject a language spoken only by one person in their environment starting around age three[1] and how you get distinct school/social class accents, like international school English or public school English in the U.K.
This guy spoke only Klingon to his son for the first three years of his life. The same rejection occurs with natural languages if only one person speaks it to a child so if you want your child to grow up bilingual they better hear your language from other people too.
