Robert Downey Jr. 'I cant wait to be a daddy again'

Robert Downey Jr. “can’t wait” to become a dad again.

The actor whose wife Susan is pregnant with the couple’s first child together is planning on being very much a hands-on father.

“I can’t wait,” says Robert, 46. “I’ve done it before although my son is 18 now so it’s been a while. But I’m looking forward to all of it including not sleeping and all the diapers.

“I’m a dab hand at diapers!”

Downey revealed the sex of his unborn baby Monday night on the Tonight Show with Jay Leno.

“I am not permitted to discuss it,” he quipped. “I can’t say a word… We’re having a boy!”

Donwey said the baby is due in “late February”.

“I don’t wanna be presumptuous,” he joked. “But I think actually [the pregnancy] has been tougher on me [than Susan!]… Just the hormones on and the mood stuff and the nausea and the whole thing.

“I gotta be careful. I am gonna have to see my wife some time after doing this segment with you, and I think I’m already in trouble.”
