John Stamos and his wife Caitlin McHugh want more kids.

The happy couple welcomed their first child, a son named Billy, into the world in April this year just two months after tying the knot in February, and it seems they're already thinking about baby number two, as Caitlin says she wants more children ''as soon as [she] can''.

Asked when the couple might have a second child, Caitlin said: ''As soon as I can! Right now, Billy is extremely spoiled and we need to share the love, he's gotta share some of those toys and all the things that have been given to him. He needs [siblings] to keep him grounded. If he's the only one, he'll get way too much love because there hasn't been a child on either side of our family in quite some time.''

Whilst the couple's top priority is for their babies to be born healthy, 32-year-old Caitlin admits they would ''love'' a daughter.

She added: ''I would love to give him a little girl, but we're happy with boy, girl, just healthy.''

The 'Fuller House' star, 54, and his wife are loving their new lives as parents, and find everything Billy does to be ''adorable'' - even the gross stuff.

Caitlin said: ''It's adorable. Even all the gas and stuff, everything he does is exciting. It's like, 'Oh yes, you pooped! That's great! You farted, that's great! You burped, right in my ear! You spit up in my face and I couldn't be happier. There's a lot of positive reinforcement in our house for literally everything.''

And Caitlin is amazed at how her spouse has transitioned into the ''perfect father'', as he now takes on diaper duty without any fuss.

Speaking about John to 'Entertainment Tonight', she said: ''He used to say he's not going to change any diapers ... and he's changed so many diapers! He totally doesn't mind it. It's beautiful seeing [John] with Billy. It all feels so right. It feels like this is the way it should've always been. He comes so naturally to fatherhood and I love watching it. I stare at the both of them all the time. [John is] 100% full-on active and fantastic ... He's perfect, he's a perfect father. I can't wait to give him more [kids].''
