Los Angeles:
The 40-year-old star - who split from 23-month-old Ethan's dad Kris Smith in April - says the youngster made her appreciate how lucky and "blessed" she was when she was at her lowest point after her break-up.
She told Australia's InStyle magazine: "Life has been full of certainties and surprises but, even with the changes, I know I am incredibly lucky, and wake up each day feeling blessed with my beautiful baby boy there.
"When I tuck him into bed, I'll hear this little voice yell out, 'I love you more!"
Despite his young age, Dannii - who is rumoured to be close to reconciling with Kris - thinks Ethan is already showing the signs of following in the footsteps of herself and singing sister Kylie Minogue.
She said: "He knows if he says something with particular timing he can make you laugh, melt or whatever. I guess that's the Minogue performer inside him!"
Former X Factor judge Dannii reportedly reunited with Kris recently after they realised how much they hated being apart.
An insider said last week: "They both realised how much they missed one another. Neither of them could admit it was 100 per cent over - they just couldn't let go.
"They both love Ethan, and having to act as single parents was breaking their hearts."
