Reddit reviews Pirate Pete I Am a New Big Brother

We had our second around the two year mark and Pirate Pete was the favourite book of the time (exciting new things, focus on the child not the baby)

But these days (age 5) the Osborn series of lift the flap books would be better received (i.e. whats happening inside) - Ive not read this one, but we have others from Osborn

Note:
The Osborn book has been flagged for inappropriate language by one reviewer, to which I would say, "What world do you live in where you can skip the body parts that having a baby requires?".
Also, one review says the "See inside the body" book contains the same pictures, but ours does not cover pregnancy (but is a worthwhile book to buy in any case)
