A source tells ET on Thursday, "The boys are in school and with their father. Britney always puts the kids first and chose this time to get help while they are with their dad. [The boys] have not been disrupted because this is their time they are normally with their father."
"Britney knows the boys are safe and happy and well taken care of with him," the source shares. "This is truly a loving family that works together so that Britney can give herself this time to heal."
Late last year, Jamie was rushed to the hospital when his colon ruptured. According to a release, he spent 28 days in the hospital, and the family credited the doctors and nurses for saving his life. In January, Spears announced she would be taking an indefinite work hiatus to focus on her father's recovery. However, the stress of seeing Jamie ill has taken a toll on her.
Britney Spears Checks Into Facility Amid Father's Health Crisis
"Britney chose to enter the facility and plans on taking at least a 30-day break to focus on herself," the source tells ET. "She plans to remain in the facility to help reduce her stress level and get her strength back so she can be there for her father and kids."
"Her father's health [crisis] has been very difficult for Britney to watch because he has been struggling," the source continues. "He truly is under the very best care and Britney knows that. She also knows it is out of her hands and she needs time to heal right now."
The source also adds that their entire family "is incredibly worried about Jamie." "There has been a lot of tears during this time and they are all leaning on each other for support," the source says. "They are making sure he has the best care possible and they show him every day how much they love him."

He wishes everyone well."
