The `Australia`s Got Talent` judge has been focusing on getting back to full health after being diagnosed with an underactive thyroid but she admits she and partner Kris Smith have discussed the "possibility" of having a sibling for their 16-month-old son Ethan.
She said: "There`s the possibility of a bigger brood. The main thing has been getting my health back on track.
"But I do look at other little babies and think, `Aww it`d be nice to experience that again.` So yeah."
Dannii, 40, loves being a mother but says she seeks guidance from Kris and her brother when she is unsure about parental matters.
She told Now magazine: "Kris knows it all and doesn`t have fears about anything. I`d never been around kids before, so he`s teaching me along the way.
"I ask my brother for advice. He and his wife have two kids and are always bringing toys around for each stage Ethan`s going through. As a parent, sometimes it`s so confusing. I go to a toy shop and don`t know what he`d like or what he needs."
