Finally, when the poster and their mom told her to stop, she begrudgingly agreed and the poster hoped that would be the end of it

She added that it could be a way to deal with stress or insecurity, giving them a sense of comfort. The poster also mentioned how Alana has always been infantile, and even theirmothertakes her side, so she might not feel like she’s doing anything wrong.

However, the poster and their other sister, dubbed Este, find it really annoying and they have called her out on her behavior multiple times, but Alana finds it “cute” and refuses to stop.

Muskan explained, “When parents take sides, it often creates bitterness and tension. It can make one sibling feel unsupported and make conflicts worse. Staying neutral and helping siblings talk things through is usually the better approach.”

Maybe Alana would hesitate if her mom stayed neutral in the situation—she actually listens later when the poster and their mother both tell her to stop. However, before that, when Este and OP told her to quit it, she used some lame excuse that they had used it with their kids, making many Redditors question her maturity, and wondering why she saw herself like thekids.

She even went on to ask Alana whetheranxietywas causing her to do it, but Alana was offended that OP would diagnose her with something. However, at the end of that conversation, she listened to OP and their mom (who was surprisingly on the poster’s side, finally) and said she would stop.
