Language / "Putschke" - Please help me figure out a nickname my grandfather called me [30]

My grandfather passed away when I was very young. Before he passed, he gave me some gifts personalized with the nickname "Putschke." He spoke Polish, Yiddish, German (Austrian), and English. Could "Putschke" be a Polish word, or a misspelled Polish word? I've been trying to figure out the meaning of this word for years. I was the only grandchild my grampa lived to see, so it must have had some special significance for him. If it helps, I am female.

Thank you for any help you can provide!
