to include the teaching of my mother tongue in our homeschooling curriculum.
take my kids to the village at intervals to encourage them to speak directly to those from their kin.

Blessings @inspiredbyhive!!With the steps you have followed to include the mother tongue, I'm sure you will get excellent results, taking them to the village to talk to their kin and learn about the geography of the place will motivate them to learn.

Greetings!
