The excited dad over the weekend shared an adorable photo of his newborn daughter with the caption: "Today you are already a week in life and we have a few dark circles under our eyes! Other than that, only happy! #daddysgirl #happierthanever #petrouniasfamily"
Last week, Petrounias announced the joyful news in a moving post. Instead of baby gifts, he urged his followers to donate to charity.
"December 3 23:57 our Baby got her little sister!! Double the joy, double the blessing to see our family grow. Thank you all for the wishes!! Flowers and teddy bears are always welcome but at this time we would ask you to donate this amount to SOS Children's Villages to make other children happy during these holidays," he posted.
"We thank our Doctor Panagiotis Betta that we feel so safe with, our Maia Gogo but also the staff of @omilosiaso" he added.
For those who would like to donate, please visit SOS Children's Villages.
Congratulations to Vasiliki and Eleftherios on the birth of their beautiful baby girl!
Na Sas Zisi!
