I always feel when it comes to these big life decisions that God seems especially silent.
So, you have experience with God being "silent". Possibly you already have discovered how it was best to handle this.
Even so, I think of how God can seem silent, but really He is quiet while we can have noisy stuff in us keeping us from communicating with Him.
And He might want you to discover how things are going to work. Actions can speak louder than words.
And He could want you to have communication with your husband about this. But yes indeed sharing with your family can be a higher priority and benefit.
Doing things as family might help to feed you for how to do things as a teacher. After all, our God is our Father and Jesus His Son. Man made in God's image is a multi-person family being.
And so, your teaching could go better in a Christian school or Sunday school where family relating would be welcome more fully. But God is not limited.
About how to teach > you might consider how babies have become able to speak any language, while students in schools often can be all but clueless about how to speak a language they have studied even for years.
How is that?
My niece's girl has been doing Spanish for years and she got tongue-tied when I said a very simple thing to her. But my pastor's daughter-in-law is conversing in Chinese and English with her two pre-school children.
One thing is that a baby learns in a family. There is individual attention. The baby can get praise and delight for making any noise, at all.
There's no theory or set, one-size-fits-all methods. It's a family exciting thing even for everyone. And the other children help the newer child to learn; this can strengthen the language ability of the children who help the younger ones.
You can learn a subject or activity better in helping others with it . . . in giving. And if you are dearly loving the one you teach, this can have things work even better. Family loving, then, has much to do with helping the baby to learn any language, and even be bilingual.
And it is used, right away.
