I am looking for a book to get DS who will be 3 when the baby arrives talking about being a big brother to try and prepare him for the baby and get him involved. Any suggestions?

Re: Those with a child already
I second this! He is 5 and he gets it but I would like it to be more real for him.
Missed M/C discoverd at 10w5d measuring 6w6d on 12/3/10 said goodbye 12/12/10 EDD 6/26/11 "this too shall pass"

My daughter will also be 3 when baby arrives. I have "I'm going to be a Big Sister" (https://www.amazon.com/gp/product/097671986X) and "I'm a Big Sister" (https://www.amazon.com/gp/product/0061900621).
She loves both of them. Obviously one of them is more prep than the other, but I think they're both very appropriate. Teaches kids what toys babies can/can't play with, what they eat, that they cry, that they require attentions...I'd say age appropriate for 2-7 or so.
ETA: They both come in boy versions too, obviously!
We bought this one for DS last time and he really liked it.
Edit: Same as others listed.
Baby Boy loved for 15 weeks, 5/31/11
Baby Girl loved for 16.5 weeks. 3/1/12
The one listed is the same we got for DD the last time, we used the book as a way to tell others of the pregnancy. I tucked it away in a drawer and will bring it out again when I feel more confident in things.
We have this one:
