I have no idea if they're legally married or not, but Kurt's ring must have been worn to incite speculation and increase engagement. The ring switches fingers and then appears to not even be the same ring. They know what they're doing and they're either eating up the attention or acting totally annoyed that people would speculate and notice such a small detail.
I hope she sincerely thanks her parents for taking care of Fox so often (and often at a moment's notice). That's such a huge blessing and a luxury that so many parents don't have. I hope that behind the scenes she expresses gratitude for all that they do or at least pays them.
She really isn't like other parents. No matter how hard she tries, she won't be relatable ever again. That ship has sailed. Dropping your kid off with your mom several days every week (even when he's sick) so that you can go workout or have lunch with your partner isn't relatable. Heck, having lunch with your partner in the middle of the day during the work week isn't relatable. She's not being real. She's just putting how spoiled and privileged she is on full display. It's awesome that her family is there to help and I don't think it's a jealousy or envy issue for most of us. I just hope that she expresses immense, sincere gratitude for having the support system that she has. However, perhaps she could flaunt it a bit less? Not that it would help her image at this point, but maybe it'd be a tiny show of respect for those of her followers that are not as fortunate to have a loving, attentive, supportive family.
Edited to add: I actually love that her mom takes care of Fox because he is so well cared for and stimulated. He seems to developmentally thrive when he's with her, so I think for his sake, the more time he spends with his grandparents the better. He seems like such a happy baby when he's with them, so it's great that he spends a lot of time over there. Just wish Sarah would be honest about it all.
