Bi-Lingual Babies

So, I speak spanish. Not fluently but pretty good. Good enough to practice law in spanish. I never thought much about my kids speaking spanish until lately, for a few reasons. There's a daycare at my job for kids of employees and all the little kids there speak spanish. Also, my kids hear me speak spanish to them and they can't respond or don't understand.

Lately Eli has taken to throwing a rolled "r" into words and then saying, "look mami i speak spanish" i.e. "water-rrr" is water in spanish or "thrrrree" is three in spanish. It's cute but kind of sad because it is a part of his culture and everyone in his direct lineage speaks spanish (except for my mom).

So now i'm wondering if i'm doing my kids a disservice (sp) by not teaching them spanish now or should i leave it up to them if they want to learn later? knowing spanish has helped me in life so i'm sure it will help them but i didn't start speaking until i was in my 20's. and how do i make the switch now? I'm thinking i should change their daycare and start bringing them here because they'll be surrounded by it.
