As news.com.au reports, Bickmore suffered from mastitis and post-partum haemorrhages after Oliver's birth.
“Ollie we have been on a big journey together honey, but raising you has been the easy bit. I never take for granted how lucky I am to have been given the chance to watch you grow up...you are the kindest, happiest, funniest, and most resilient young man,” the caption continued.
Bickmore’s former husband Greg Lange—father to Ollie—died of brain cancer in 2010.
“Your dad would be so proud of you who are,” Bickmore added in the post. “Mummy, Chris, little Evie, your grandparents, aunties, uncles and cousins love you 100 times more than you love watching people play Minecraft! A lot! here's to many more years of life together beautiful boy. Happy 10th birthday.”
On Sunday, the TV host also shared a Father’s Day snap of her partner Chris Walker, their daughter Evie and Oliver taken 18 months ago. Adorable!
