It is easy to get overwhelmed while teaching kids especially toddlers. Please check this tread. Few parents have given good schedule guideline.
http://forum.brillkids.com/general-discussion-b5/day-schedule-for-21-22-month-old/I try to do math and english flashcards everyday. We speak with them in English and in Indian language. I do Indian languege flashcard over the weekend (usually dont do math and english flashcards on weekends). If you are pressed for time, try to do 2 things on weekdays and 3 things on weekend. Also you can try reading a book during bed time. That will cover english / chinese reading part for the day.
Hope this helps.
