It's the second time too.
I've always wonder why Mindy and Shaun decided to have 6 kids when they only seem to give a damn about the older ones. They take every opportunity they can to leave the younger kids.
It has been discussed before but I will sum it up.
Mindy and Shaun had the twins, Brooklyn and Bailey. They then had Kamri and Rylan.
When Mindy was pregnant with Rylan, she was expecting twins but Rylan’s twin died so it was only Rylan. Shaun and Mindy were expecting to be a family with 5 kids but that didn’t happen. After having Rylan, Mindy went on birth control (IUD). She later decided to get the IUD taken out but failed to get pregnant so they looked into adopting a baby boy and that is where Daxton came about.
A few years after the McKnights adopted Daxton, the adoption agency or the biological mother (I think?) had a baby girl (Paisley) that was related (?) to Daxton as his cousin (?) and asked if the McKnights wanted to adopt her. I believe they wanted a sibling for Daxton so they got Paisley for him.
