The 49-year-old, who has three daughters Rumer, Scout and Tallulah with ex-husband Bruce Willis, don't want to deal with the drama at the moment, reported Radar Online.
"Rumer, Scout and Tallulah just don't want to deal with the drama at the moment. Since breaking up with Ashton, Demi has been a mess. The girls were there for her through it all - the split and the rehab but now they just feel like they need a little distance," a source said.
"Demi is just being very needy right now and the girls are tired of it, they want a mother not another little sister. They are all concerned that she is going to relapse and head back to rehab and they can't deal with the stress and worry of it," the source added.
Moore split with Kutcher, her third husband, recently amid claims that the actor cheated on her and since the split Moore has been keeping a low profile.
Last month Moore collapsed at her home and she was rushed to the hospital and subsequently entered a rehab treatment center to deal with her substance abuse problems and eating disorder.
