Matthew Broderick makes up his parenting decisions as he goes along.
The 'Wonderful World' star, who has three children with 'Sex and the City' star Sarah Jessica Parker, has confessed he is learning how to be a better dad every day.
He said: "I love being a father, but I don't have any advice about it. I guess I could say the same thing about my marriage, basically.
"It just develops and changes and I'm very lucky with who I ended up with. And we've been together a pretty long time."
Discussing his new twin daughters Tabitha and Marion, who were born with the help of a surrogate, Matthew said they were "very easy to take care of".
The 47-year-old actor - who also has a seven-year-old son James with wife Sarah - added to Parade.com: "They sleep through the night now. But they had colds over Christmas and they would wake up every two hours coughing.
"It's really hard because one would hear the other cry and start crying too, so that was absolutely exhausting. But I won't lie, we have plenty of help because you can't really handle them alone."
Sarah, 44, has previously admitted she was unsure about having twins.
She said: "We didn't want twins but we wanted a bigger family and this is what we got."
