Julia Stiles has some fierce advice to those criticising her photo with her baby.

In October, Julia Stiles – of 10 Things I Hate About You and Save The Last Dance fame – welcomed her first baby with husband Preston J Cook.

Strummer Newcomb Cook was born on October 20, and was described as an “utter joy” to his parents.

Four days ago, the new mum shared a cute baby snap on Instagram, and the Internet tried to turn her joy into a nightmare by leaving unwelcome advice on the post, shaming the 36-year-old for her parenting style.

LISTEN: Should you have visitors in those early days with your new baby?

In the picture, baby Strummer is cosied up in a front baby carrier, his head tucked into his mum’s chest and his little feet hidden from view.

I haven’t worn a back pack since middle school. ???? Now I have a front pack. #jujube #tulababycarriers

But ‘fans’ were quick to comment that baby Strummer was far too little to be in the carrier, and that the actress hadn’t placed him in correctly.

“The baby is too small for this carrier,” one person wrote, while another commented, “please pull babies legs out for proper placement.”

“Congrats! Beautiful new momma! Tula tip: Little baby feets go out the sides and not in waistband!” said another.

But Julia had a message for her critics, and it went a little something like this:

In other words, she expertly clapped back.

“It was brought to my attention that in the previous photo I am not holding my baby correctly. Wow, I didn’t expect that,” she shared on Instagram.

“What was supposed to be a shout out of products I like, suddenly becomes an invitation to comment on my baby, and my ability as a mother. That’s the internet for you, the carnivorous plant from ‘Little Shop of Horrors’.”

She also confirmed that she had specifically placed her baby’s feet and head away from the camera to protect his privacy.

“I was trying to keep much of my son’s image private, including, I guess, his little feet,” she said.

Strummer Newcomb Cook, born October 20, 2017. Thanks and ever thanks to the extraordinary Doctors, Nurses and staff at Mount Sinai for helping bring this utter joy into our lives. ❤️✨ “Hello, World!”

“And it was just a photo taken at home, not how I normally carry him around. Thanks for the concern, anyway.”

She also had some wise words of wisdom of herown for the ‘parenting experts’ that have been stalking her account.

“Instead of writing snarky comments about a 5 week old, try dancing around your living room to a Clash record. It’s way more fun.”

Julia’s account was soon flooded with praise for her response, with many saying they followed her specifically after hearing of her no-nonsense approach to mummy-shamers.

“With all the negativity being spread online I wanted to come on this post and say your doing an amazing job as a first time momma,” one fan wrote.

“Clearly people have way too much time on their hands while you are smashing life and enjoying your newest family member,” said another.
