Adrienne Hedger is kind of a pro at celebrating birthdays during the holidays .

The cartoonist, who shares her work online under the name Hedger Humor , was born on Dec. 24, and her youngest daughter was born on Jan. 4.

Whats tricky about that, she said, is the planning and the invites all have to go out at the exact same time that everyone is completely focused on the holidays.

In 2015, Hedger created a cartoon inspired by a conversation with her daughter that summed up exactly how she felt about planning a birthday party for a bunch of kids at the height of holiday mania.
