"He would just rip it straight down," she said.
The actress practises baby-led weaning and says before she even starts a movie, she sits down with the director and producer and explains to them that this means her son is going to be on set.
"That's honestly my key when parenting, and it always has been. We choose to co-sleep, we do what is called extended breastfeeding which to me doesn't feel extended at all, it's just meeting his needs," she said.
The actress, who has nine films coming out over the next year (including a remake of hit '90s film Point Break), says her son is used to being able to call out for his Mum when he needs her.
Her concern is that the taboo that still surrounds breast feeding could be damaging for new mothers.
"I think it's really detrimental to some women who are starting their breastfeeding journey with their babies, and feeling any sense of shame," she said.
She takes her cues from her son and acknowledges she has been lucky that she has been able to maintain a career and practise the kind of parenting she wants to.
"Everyone knew that I would breastfeed him whenever he needed it, obviously not in the middle of a take but in between set ups he'd be around and everyone on the crew would be holding him," she said.
She believes the only way the stigma will be broken will be when people finally stop talking about it.
"I just can't believe it's still a conversation. Until it stops being a conversation then it's always just going to have some sort of taboo feeling surrounding it, " she said.
Before her little boy even came along, Palmer had the the opportunity to work in her home country shooting Kill Me Three Times in Western Australia.
Filming the dark thriller, which focuses on murder, blackmail and revenge, brought different parenting concerns for the actress, who was six months pregnant a the time.
"I'm playing this murderous woman who doesn't have a compassionate bone in her body, and meanwhile I have this beautiful little peaceful being in my belly while I'm playing this horrendous character," she said.
"So I would, at night time, I would go home and talk to my belly and tell Bodhi 'Mummy loves you, don't listen to what's going on at work'," she said.
Luckily, she says, he seems unaffected and is a happy little guy and the LA-based actress says she was happy to have the opportunity to film at home.
"It was beautiful and I loved the script, I thought it was just crazy and gritty and dark and funny," she said.
"It's offbeat, I love that offbeat humour."
She says she will be filming two more films in Australia over the next few months.
"It's so nice to come home and support the Australian film industry and I just love the crews, they're my favourite," she said.
"I love just being around my people."
* Kill Me Three Times releases on September 9 to digital download, DVD & Blu-Ray.
