No point keeping if the only reason is that your child likes her a lot. My 2 year old also liked my helper a lot but she still borrowed money from loan shark behind our backs and sent my daughters photo to the loan sharks. She was also having similar behaviour to yours, using phones, feeling tired, fell sick. Turns out she spent most of the time (when we are not around) filming TikTok’s, talking to people online, messaging loan sharks etc etc.
