My baby was 5 month, i also found my maid , carry my baby and sleep in my sofa, through my Icam while i am at work.
I phone her and wake up her at once.
then, I go home n let her know I saw her sleep
remind her be careful,
then request her to go to bed early, keep more sleep.
Overall, my maid is OK, she is not lazy, not talk on phone, so ask her to take a rest is a solution.
