The 33-year-old actor is busy shooting his new movie 'Jupiter Ascending' in London, and although his three-week-old baby girl Everly and his wife Jenna Dewan-Tatum are with him in the UK capital he still misses them while he is on set.
He told E! news: "I'm away from her for 12 to 13 hours (a day) and I feel like I come home and I feel like she's changed - like her face looks different. You feel like every minute that you miss is horrible."
Channing conceived his daughter when he was filming 'White House Down' which shows a Capitol policeman that has to save his daughter and the President of the United States from a paramilitary group.
He continued:"Jenna [Dewan-Tatum] and I weren't pregnant then, but we conceived on that movie. So it's kinda crazy that I had a daughter on the movie ... and now we just had our own little, cutest, most amazing thing ever."
Talking about how his wife Jenna is coping with motherhood so far, he added: "She's good, she's really good. Tired, you know ... just taking care of the baby on those first months is hard."
