animals r scary?

brought my lo (1yr 4mths) to the zoo and I think she got frightened cause she sleep and keep making crying noises in her sleep. I made sure she napped and she didn't exerted lots of energy too but she did come close to an orangutan.. which I too feels it looked quite frightening... LO wasn't afraid to go near the glass for the snakes and big cats.. only the monkeys hahah
