Helper overly enthu

Hi, I recently had a helper just for my new born. She seems “overly enthusiastic” with my child, whenever my new born started crying, she is in the room carrying him, and didn’t wanna pass my new born to me since I’m there (even thou after her). Shld I b worried? She also seems to be on her phone frequently too, saw that she is on the line with ear bud on all the time.. and keep using the xiaomi vacuum almost 3-4x a day without physically mopping
