Despite the fact that my boys are now 8, 8 and 10 I still read aloud to them as often as I can during mealtime.  My purpose is fourfold:
1) to keep them from speaking! :)
2) to change the topic from poop or boy 
like banter to something more sophisticated, education and/or interesting
3) to promote "normal" conversation
4) to teach!!
Most recently my husband and/or I have read three books aloud:
1- Wright Brothers - aside from the interesting and constructive conversations these young siblings/engineers have about their continually evolving business ventures, the intimacy and reciprocal respect they have for each other is remarkable and touching! Very inspirational for brothers.....and they have a sister who takes part as well, mostly toward the end.  
2- Escape from Egypt - a close up encounter of two children "flown" back in time to the days of Moses prior to the ten plagues.  A compelling account of the incredible hardships of slavery and ultimate escape to freedom, with humorous references to modern day technology and the lack of knowledge the ancient Egyptians had of it.
3 - Joe DiMaggio - what resonates with me here is the "old world" beginnings....an immigrant fisherman with many mouths to feed, unwavering in his expectations of his children to want to continue to live life in the same manner through to the next generation.  Not knowledgeable of baseball nor willing to become a fan,  he finally concedes and cozies up to his newly famous son Joe....a touching ending for the entire family.
