We own all of them except the Dino one due to the millions of yrs and how they were destoyed. We love them! The boys have read them and re-read them a good many times! They have learned so much from them! And the dvd’s, and now available on Netflix, are great learning tools! Although my 11 yr old does not read them anymore, they were some of his favorite books!
I thought that the sarcasm would influence the boys, but it has not. And they know that it is not right to speak to each other like that. Some children may be influenced. I know someone whose child picks up on all kinds of stuff and acts it out! You have to be the judge on that one!
The only other book in the series that mentions Millions of yrs is the MSB Inside the Earth. This is a great book except for that! We have taught our boys how we believe since they were small, so they are prepared when we/they come across info that promotes millions of yrs! Hey, even science museums speak of these things! We went over the summer to a wonderful museum and it was mentioned all over the place! Oh and I forgot it was even at the Aquarium we visited too! I say this so you can help prepare your children ahead of time to know that they will enounter these things in many different ways, not just in books!
That was my 2 cents 🙂 And yes they are twaddley, but fun and full of info!
