Has anyone out there taught their baby two languages?

We're teaching my 19 month old daughter english and hindi. She gets plenty of english exposure, but I'm wondering if she gets enough hindi. Only her father speaks it. He teaches her little phrases, she knows eyes, nose, blink, ceiling, come here, boo, aunt, and give me. She watches a few hindi songs for kids on youtube. That's it. Is that going to be sufficient to learn a second language? What have you all done to reinforce your child's second language?
