Emotionally sensitive toddler?

Denise

My LO got her 2yr old shots 2 days and she's still traumatized by it. She's now terrified of her crib and bathtub for no other apparent reason other than she's thinking about getting shots. She keeps saying "no more shots" and 'I got scared'. Anyone else have an emotionally sensitive LO? How do you cope? How do you help them?
