The new parents first announced the exciting arrival on October 22, when Jen posted an intimate picture of Frankie nestled in her chest.
"Frankie Violet Hawkins Wall 💓💗💗💕✨ Dream come true! So thankful to be holding our beautiful healthy baby girl! We couldn't be more in love," Jen captioned this sweet photo.
Since then, the couple are clearly in the new baby bubble - posting sweet pics daily.
Earlier this year, Jen opened up for the first time about her fertility struggles.
