Hi
I have posted around 10 words from YBCR starter DVD on the wall, high up, covered with a piece of paper. At times I just take my kid in my arms and we go around playing peek-a-boo with the words. I keep it fun and he likes this. It acts as sort of review. I change the words now and then with another set or shuffle them. I make sure that he just has a glance of the words, so that I don't have to worry of over exposure. It has been going on fine till now.
