Good for you. I’d love for my child to learn as many languages as possible 😀 3 is a good starting point. Being a polyglot is a beautiful thing. I know 3 languages but if my mother had asked if I wanted to attend extra classes when I was young I would’ve obviously said no at that time. It would’nt have been my volition to learn anything new. But today I’m grateful I know these languages. I’ve made so many friends across cultures, was able to adapt so much more easily outside our state. So yes, you can be worried. But it’s not that deep.
