What’s your way of studying languages?

I use Pimsleur. I have a 4-month old that takes forever to take his bottle. So, I play the Pimsleur audio while he eats. Both take about 30 minutes. He will benefit as well as he gets to hear it along with me. I also have other apps that don’t require much time while he naps. When he wakes we read and sing in Spanish. So we are both picking up vocabulary.
