The actor shared pictures on Instagram from the festivities, where Billy was all smiles as he played in the room full of bubbles. The father-son duo was joined by Stamos' wife Caitlin, his sister Alaina, actor Josh Peck and more. "Celebrating early 'Billy Birthday' courtesy of his beautiful auntie @alainastamos and @thediscoverycube - We LOVED #bubblefest THANK YOU for a Wonderful Day!" the proud dad captioned the post. Emmalee Mang Stamos also spoke to PEOPLE last summer about life at home with his little boy, calling his family of three a "dream come true," especially considering the actor once believed having a family wasn't in the cards. "I always wanted to have kids, but I didn't think I'd meet the right person," Stamos recalled. "And maybe I felt like well, I have everything, I shouldn't be greedy." Ultimately, Stamos said he attributes finding his wife to "straightening up my life." Said the actor: "I wasn't deserving of it yet I think. But six years ago, I sobered up and I became a better person. And when Caitlin came around, I recognized it immediately. I said, 'I have to be good for that to make it work.' "
