"With Calvin and Oliver there was no family connection whatsoever, we just liked the names. But when you have a third boy you're just out of names completely," Dylan explained.

"We just thought it would be really special to use both our dads' names. Russell is Brian's dad's name and James is my dad's name. it was really special to tell them, and nice to see them cry and tear up a little bit. It's hard to make grown men cry!"

Rusty is doted on by his big brothers too, with Dylan revealing: "They are loving it. Calvin is so sweet, he's been through a baby in the house before so he's just wanting to hug and kiss him and help feed him a bottle. All these things he can't wait to go home from school and do.

"Ollie was my curveball, I wasn't sure how he would handle it but I think from watching Calvin he's learnt that the baby's not a threat. There's enough love to go around so he's adjusting awesome. I couldn't ask for a better situation. Everybody is just so happy."

"It's nerve-wracking as I want everybody to like it as much as I do. So far the reaction has been nothing but positive," she said.

"It's fun for everybody to get athe copy and read it and just so cool to imagine people reading it to their kids. You're putting yourself out there and it's just nice that everyone has liked it so far."

One thing Dylan is yet to do that's high up on her list is to take her oldest son to the local book store to see his mom's book on the shelves.

Dylan's son Calvin has had a big role in his mom's book

"It was so fun when we had the final copy of the book and to see the artwork come out, then the coloured artwork and now the actual book. The excitement for him when I opened the book – I wish I had it on camera as it was so special. He has been a part of this whole ride."

It's safe to say that Dylan's book's biggest fans are her sons too. "Calvin has seen it the whole way through and just to read it to him, and have Oliver now want me to read it to him, I can't believe I am sharing it with the boys. It's amazing!"
