You’re doing something really meaningful. Choosing to homeschool especially in a second language and with special needs in the family is no small task, but it’s clear you’re doing it with love and intention.The phonics-based course sounds like a smart choice, especially since it could benefit both of your sons in different ways. Yes, there will be challenges language, time, resources but you’ve already taken the first, most important step.
Just remember: it doesn’t have to go perfectly. What matters most is being present and committed. You’ve got this and you’re definitely not alone.
