OK, I have lots of professional knowledge & experience in this regard. This is my opinion, take it for what it’s worth (or not worth in your opinion).
These pictures area from Thanksgiving Day 2016. So Bella was 2 years old & CeCe was 1. They both appear to be receiving a punishment of standing with their noses in a corner. I will give the benefit of the doubt & assume a 1 year old is not being punished in this manner, although IMO the post does allude to that.
Even if it is just 2 year-old Bella, a pediatrician, child psychologist, or any other professional with deep knowledge of child development would tell you this is not age-appropriate.
Toddlerhood is a particularly vexing time for parents, because this is the age at which children start to become more independent and discover themselves as individuals. Yet they still have a limited ability to communicate and reason.
I’m not stating this to cast judgement on posters who have done this to their own children. I’m looking at this & other things I know & have observed of SW’s parenting style & addressing how this may fit in with the bigger picture.
According to the American Board if Child & Adolescent Psychology, “Time-outs may not be the best approach for the toddler stage. The negative implication of being sent away can teach kids that they're bad rather than promote good behavior. At the toddler stage, we recommend parents instead try redirection, as it is far more effective than discipline tactics at this age.”
For example, a cozy corner for the child to look at a book & take a break, usually a minute per each year if age (2 min for a 2 year old, so to speak).
Add to this the fact that the children were publicly shamed by these pictures being posted on SM.
I’m not diagnosing SW by pictures & videos alone, but there are many things (this, the Xmas video with her becoming angry with Bella for not enjoying the experience & repeatedly calling her names, the video where she allowed CeCe to put herself in danger climbing to “learn her lesson,” etc) that raise red flags for me knowing what ultimately happened to these children.
