Sarah and Aiden headed next morning to meet with their kids.
As much as they wanted to stay in Los Angeles and find out what JoAnna recommends for Charlie's treatment, meeting kids took priority because they have a lot of newcomers. It's important to be there and make sure they know the rules and to set expectations from the start. They can't rely on their seven kids and house staff to do that for them.
When they arrived in United States from Sierra Leone, Sarah and Aiden left all the kids (and Jesse) at their beach house in California, told them to rest and eat and that they will be back in two days. Staff in the house was instructed to take care of sleeping arrangements and clothes for the newcomers, and to make sure they get their meals on time.
