Help! Suggestions for crying baby...

Hello everyone, my 9.5 month old has just become very interested in the YBCR flash cards. Though he’s been watching the videos almost every day since 3 months he was never really into the flash cards and books that accompanied the program. But, now he loves the flashcards…problem is (or maybe not a problem?) that after I go through all the cards with him he cries because he wants me to do them again. Sometimes I do them 3 or 4 times in a row and he still can’t get enough! I’d be happy to go through them over and over again but I just don’t know if that’s correct (is there a wrong way to do it?). Does anyone have experience with this? How did you handle it?

Thanks for any advice you may have!
