My toddler likes to pretend to kiss me and instead bites my cheeks. When I yelp she laughs. It's actually not funny. And when I shout at her she laughs more. This has happened many times. She knows it hurts me. She does not do this to anyone else. Does my baby hate me, so chooses to hurt me? Or am I reading too much into this? Also can someone tell me how to make her stop.

ouch, that must have hurt a lot :( But hey, they are still young and innocent. Believed she is laughing at your reaction... perhaps you can teach her how to lessen the pain by blowing or lightly patting the 'injured' cheek after the bite? Perhaps to divert her attention, you can show her some bigger reactions from you with less painful results? Some clapping games, light pats on the mat etc to trigger sound effects and laughter from you? Or introduce her to some musical instruments?
