"Happy #sunday @rlsmodelsphotography God gave me an extraordinary young lady @sophialabraham I'm so blessed - excited to see all the great things flourish in Sophias life journey #blessed #beauty #photography," Abrahams captioned one picture posted overnight.
"Something is wrong with you and your family. This poor child is doomed," Twitter user Rosie said.
"Wow, whoring out your 6 year old (sic). A new low!" wrote Uncle Dave's Dad.
Vivi Perez said: "It's nice you're getting her into modelling, but in this pic she looks too old for her age. Kind of creepy."
Suzanne Zaretsky noted; "This is a disturbing photo of a very young child."
And Loretta Johnson warned: "Watch out for sickos to go after her. Its (sic) scary in this world with kids. Too many pervs."
"Gosh I thought she was about 25. You should be ashamed of yourself," offered Louise Mary Fagan.
"I can't believe that she has Sophia modelling. Children's modelling includes clothing brands stores or toys. Not photos on the beach up against trees and a pose in the water.
This is sick and I truly do feel horribly bad for Sophia that she will be raised this way."
DrNicole said: "first she is not cute, she looks 40 you are a horrible mother and I pray she gets a hell of a foster family one day."

The latest photo was posted overnight despite the negative reactions Abraham received after sharing pictures of Sophia, who turned seven in February, wearing a bikini poolside during a shoot for Child Model Magazine on Friday.
The 25-year-old has had a love-hate relationship with the public since shooting to fame as a star of hot reality show Teen Mom. Her tragic history - Sophia's father Derek Underwood died in a car crash while Abraham was nine months pregnant with her - has been overshadowed by her controversial career.
As well as winning roles on a handful of reality shows, including Couples Therapy and Celebrity Big Brother, Abrahams has made two films with porn star turned accused rapist James Deen entitled Farrah Superstar: Backdoor Teen Mom and Farrah 2: Backdoor and More.
Critics accused her of sexualising Sophia - something she has been accused of repeatedly.
Last month she received death threats and calls for social services to remove Sophia from her care after posting a photograph of her using playground equipment and likening it to pole dancing.
In 2013, Abraham made headlines after admitting to waxing Sophia's eyebrows - when the girl was just three years old.
"People just kept commenting on a unibrow," she explained on Good Morning America. "And I was like, maybe I am letting it go too far."
In a blog post on her website, Abraham explained that her daughter "freaked out" when she put a dab of wax on her eyebrows, so she ended up tweezing away the unibrow while Sophia was asleep.
"If I can help my daughter in a little way by just plucking a few hairs ... I think I did something right," she said.
