"I went around the corner to be a bit private and I was breastfeeding and this orangutan locked eyes with me and came over to check out what was going on," she told 774 ABC Melbourne.

"It started off with just one, and then another one came over who seemed to be a bit older and shooed this one off for a little while," she said.

"And (the older one) came over and gave me a bit of a nod."

Burrett wondered if the orangutans were drawn to watch because of her son Eli's hair, which is an orange-red color.

Other zoo patrons stopped to watch the moment as well, snapping photos of the moment.

Burrett's own mother got a picture of the encounter, which was posted on Facebook.

"Now everyone in Melbourne, well not everyone, has a picture of me feeding, as once one person saw what was going on the word spread fast and they flocked to see what was happening," she said in the post.

"I felt like I was on exhibit."

Despite her feelings about being watched, Burrett said there were no negative comments made about her breastfeeding in public.
