favourite children's book?!

What's your favourite children's book? I just need to pick on book to read to my child everyday because I've been told that if you do it while you're pregnant your baby will recognise it after they're born and it will settle them easier? Have you tried it? Let me know 😌
Ps. Preferably something short ish and easy lol. I'm going to be reading it over and over so i don't want to go overboard
