BIL wants me to teach his child Spanish and I feel like it’s an impossible task.

So my BIL (brother in law) just had a baby in the last couple of months. I am the only Spanish speaker he and his wife know but the thing is I don’t even live near them. I talk to him and his wife very often, almost everyday but only actually see them in person a few times a year as I work abroad.

I would love to teach this baby Spanish but if I’m not physically there it means I can’t do much. I sent them a few toys and books with sound in Spanish but that’s about all I can think of as a contribution right now.

I’m open to any and all suggestions on how to involve Spanish in this baby’s life when I’m not there and the parents don’t speak Spanish. The easiest one would be for them to meet Spanish speaking parents with children and have them hang out but they haven’t met anyone yet.
