Ryan Reynolds' house is filled with ''more love and more diapers'' now he has two children.

The 'Deadpool' actor and his wife Blake Lively welcomed their second daughter - a sibling for 23-month-old James - into the world in September but the 40-year-old hunk insists the new arrival hasn't changed the ''dynamic'' of their household.

He told Canada's 'etalk': ''It didn't change the dynamic. There's just more. There's more love, there's more diapers. There's more of all that stuff, you know.''

And Ryan is particularly enjoying seeing little James take on the responsibility of being a big sister.

He gushed: ''It was kind of profound. I just love watching my older daughter take care of the newborn. That's been kind of neat to see.''

While Ryan and his 29-year-old wife haven't revealed the name of their second child, they are happy with her moniker.

He said: ''We settled on the right one.''

The 'Buried' actor thinks being a father is the best thing to ever happen to him.

He said: ''It's the best thing. You know, it's the best thing that could ever happen to you.''

But he also admitted he isn't a particularly strict father as he will give in to almost anything his girls ask for.

He said: ''It's really hard to have boundaries because you just do anything they say. Like, anything they'll say!''

Ryan previously admitted it can be ''tough'' having two children under the age of two.

He said: ''[Having] two [kids] under two is tough.

''Yeah a lot of oestrogen. It's like an American Girl doll took a s**t on my life.''
