What Was Tammy & Amy’s Relationship Like In The Past

Though most viewers know the Slaton siblings from their time on 1000-lb Sisters, the duo had a successful YouTube channel before they were reality TV stars. The sisters would make fun videos together (Amy Slaton-Halterman and Tammy Slaton now have separate YouTube channel). They typically did challenges and Q&A-style videos, which were then trendy, and amassed a fairly large following. That is how TLC producers discovered them.

In their original videos, the Slaton sisters had a good relationship, which made for great reality TV. They joked around a lot. They often created silly and carefree content. Amy, who may be the villain of 1000-lb. Sisters season 4, still posts videos on her channel, while Tammy hasn’t posted at YouTube since 2021. Online, the mood grew darker, as a fan told Tammy to find the root of her anger and heal it.

1000-Lb Sisters' Tammy & Amy’s Relationship Is Different Now

Their life changes have altered their dynamic. With Tammy in her Ohio-based rehab facility for over a year, and Amy going through her second pregnancy states away, the sisters have drifted apart. Their squabbles have been tough to watch, as it seems like the two don't connect well. In an episode of 1000-lb Sisters season 4, Amy asked Tammy to make one of their classic YouTube videos, and Tammy agreed. However, it was clear that the creative spark between the two had gone out, and both women walked away looking unhappy.

Amy's tougher on Tammy than she used to be, and Tammy seems to be somewhat resentful of Amy’s rapid weight loss success, as well as her ability to maintain a growing family. Fans can only hope that the strain between the two is short-lived. Meanwhile, fans are picking on Amy over her parenting, with one remarking on a recent Instagram post, "the baby needs a bath."
