Babies doing anything is usually classified as adorable, but this has to take the cake.

In this portrait series, Pucker, by April Maciborka and David Wile, we witness the absolutely A-D-O-R-A-B-L-E reactions from babies after getting a mouthful of sour lemon.

The series is perfectly titled and something about the puckered up faces tells me these babies will be staying away from the yellow stuff for a while.

Do you have any cute reaction photos/videos of your child sucking on a lemon?
