Are you in the United States? If yes, check out your local "parents as teachers" group. Its free and designed for children 0-5 years old. They often have a bilingual play group where you might meet other Spanish speaking mothers.
I do not speak any other language besides English, so I understand. For Chinese, you might check out your local Chinese Cultural Center. They usually offer Chinese learning classes once a week and generally offer it to the public as well for a small fee. Our center offers a class for around $100 for a semster (12 weeks). I am teaching myself to speak Spanish and Chinese, and there are plenty of free resources out there.
For children, check out SALSA videos. They are free and there are 42 episodes.
