in fact, i must spend 1 or more hr to talk to my son. of course, it depends when will he go to bed. everynite i also tell him a story or told by him to me. but he always told me the same story.
My BB is only 15-mon old. I talk to her always after going home in weekdays and play with her at weekends. Same as other mothers, I don't know how much she understands!
