Do you allow your helper to kiss your child?

My child is 15months old. I have been observing her very close to my child. In fact she takes care of my child very well. But im very skeptical abt her kissing my 15m daughter. Even if its on the cheeks. Is it okay for me to feel that i dont want anyone else kissing my daughter? Or its totally fine. I have been thinking abt this and idk how to react. I meant idm her being close to my daughter but i want a limit too. Im working FT and idw my daughter to be calling her mummy in future. Therefore i try to create boundaries. Advice pls.
