TV Guide Online: Is it true what they say — that you should avoid working with kids and animals?
Taye Diggs: It was challenging just because they are children. They're finicky and they're twins. But in our case it ended up working out okay because one twin was always asleep and the other was always awake and crying. So we just interchanged them.
TVGO: Have you been upstaged by the baby?
Diggs: I don't think you can be. I'm of the school where you just let the baby be a baby. However the baby's acting, that's just where the scene goes because chances are, in real life, that's what would happen anyway. So I'm always looking forward to the baby having real moments because it just brings that sense of reality to the show.
TVGO: Ah, so that's how you got the real tears!
TVGO: Taye, how would you handle inheriting a baby?
Diggs: I'd be great. I'm the oldest in my family and I took care of all my brothers and sisters. I love children and I love just chillin' with my wife's nephews. We play, read stories, go to the park. My wife [Tony-winning actress Idina Menzel] and I are talking about kids right now.
TVGO: How many children would you and Idina like to have?
Diggs: Definitely more than one. And maybe we'll adopt, along with having our own.
TVGO: What do you imagine will be the hardest thing about being a father?
Diggs: Just letting go. I won't be able to watch the child while it's in school, when she gets to college. I don't want to be the type of parent that worries too much. But I can't imagine not worrying
TVGO: So you'll be a dad who cries on the first day of kindergarten?
