My boy is now 18mth.. shd I go and buy the whole Set of Eric Carole books? 32 titles at $100.. paperback

No need to buy any books actually, just a trip to the library will do! My son is 26mo but we're still on hard board books because he tears the paper ones way too easily, and we just borrow 3-4 books each time we visit the library - free and he doesn't get bored :)
