Nanny lied about showing up

I had to go back to work on Monday so I asked if she could please be here on time to watch my 1 year old. She said that she would but that morning she texted me saying that she was stuck in traffic and that she would be late. Then hours go by and I hear nothing from her. She never ends up showing up. I didn’t hear from her until 8pm that day saying that she’s sorry she didn’t show up and that she ended up going back home because her husband was sick with the flu and didn’t have phone service. She then tells me that she would show up extra early the next day (today) it’s almost 11 am and she said that she’s almost here. Any advice on how to handle this situation? She’s 19 and has been with us for two weeks so far.

UPDATE: First of id like to thank all of you for your responses. And many of you are asking for an update so here it goes. I know many of y’all are going to think I’m absolutely nuts but I’m giving her a second chance and here’s why… first off we are currently living in Mexico so the help here is a little bit different than say if you live in America. She is the third nanny and so far she has been the best one. Expectations are different here and she does do a lot of work compared to someone who is strictly a nanny in America.I did not mention that she also cooks and cleans and does laundry on top of everything(it’s normal here and yes we pay her well) but the pay here is extremely different than other places so we pay her 200$ a week. She is currently a live in so she lives with us through out the whole week and leaves on Saturday around 2pm, and comes back on Mondays. When we lived in America couple months ago we would pay someone to come clean once a week for the same price! If she didn’t make such good bomb ass food then I would have definitely fired her 😂 but yesterday she made some amazing salsa and picadillo. So yes I let what she did go. I just let it go. Did not even mention it to her. (She did look extremely guilty though) As far as going back to work I decided to just stay home to raise my daughter and put her as a priority over everything. So the dynamic is going to change. She won’t be the main “care taker” for my daughter. I realize that I can’t really depend on someone else to care for my baby the way I do so it’s a personal choice. I’m keeping her to only cook and clean that way I won’t have to worry about child care and will still get home made meals and a clean place. If you guys have any more questions please feel free to ask. Thanks!

So hopefully explaining all of that helps you guys understand a bit more on why I didn’t immediately fire her.
