nanny always on whatsapp

Nyasha
So my little one is 6 and a half months old and I'm a working mum so I leave her with a nanny. This nanny of mine is ALWAYS on whatsapp I don't know how to deal with this 
- I see her constantly online 
- I have a nanny cam where I see her constantly on her phone even when holding my baby (no judgements on the nanny cam 🙈) 
She will hold my baby on her laps and have her cellphone in my babies face whilst she texts 
HELP!
