If I was having with my partener the exchanges the Ingham pair has, I would be worried about the state of our relationship. It's full of passive-aggressivness.
Also Sarah hates the heat. Chris tries to downplay it but she won't go with that bs. Staying outside in the shadow cannot last more than 5 minutes according to her and having a bbq, even at night seems like to be a nightmare as it is still too hot. This will be for the whole summer.
As for the Q&A, the children don't deserve any hate. But as a parent that should make you pause and reconsider the choice to expose your own children online. If as they say they love so much youtube, they could have a cooking channel for Sarah and a DYI channel for Chris in order to protect their children from abuse and limitate their presence online. That would ask more serious work, talent and charisma than just putting a camera in front of their children. It's not happening because the only thing they have for themselves is their children's exploitation.
