"First Father's Day with my girls," the actor wrote of the photo that shows the new parents cuddling with their adorable daughter.
"First Father's Day with our lil angel!" Dewan added in her own post.
The White House Down star seems to be settling into his biggest role — Dad — quite nicely. As for his parenting philosophy, Tatum told Vanity Fair that he's going to take it as it comes.
"I don't think you can prepare. It's a bit of a freestyle," the 33-year-old told the magazine. "I'm just going to be a good friend to my kid. One thing I definitely want to change is that whole, 'I don't want you to make the same mistakes' mentality. My dad didn't have much money growing up; he didn't have much of an education. He forced that on me, and I didn't want it."
We just have to wonder how he's doing with the whole diaper thing.
"I have never changed a diaper before, so I may need some help learning," he admitted earlier this year. "But once the baby is born, I'll definitely do the diaper changing. If it means touching the poop and getting peed on, I'll still do it."
