I think all mame here are glad to share with you and will try the best to give you some opinion. Are they both Philippine? Why don't you hire different nationality? Indonesian is more pure纯品及hard working(although stupid) and they have no leave and cheaper, you can pay $100 as compensate the holiday. Are you let both of them rest at the same day? Why don't you seperate? They both think you dare not to fire them because you don't know how to manage two child. If I were you, I will warn them. If no improvement, I will fire one of them, so the other will be scared. Of course, you must have your preparation before you fire one.
My mate is Indonesian who works alone when we both goes to work.
Just read your message and want to drop you few line. No time to type chinese as I am really busy.
Well, we understand that be a working mum is really not easy! Go to work, take care baby, do housework........ really exhaused!
We love and concern our babies always, all the day. In your case, I think you should take some actions to your maids right now. It seems that they step on and you back off, again and again. Remind you that, don't let them crash your borderline as they are so smart to do so! You are advised to stand firm and speak out what is your basic requirement for caring the babies. Try to set out the timeline and guideline and see if they have any improvement on it. If they still not, you should issue a warning letter or even take dismissal action.
Cheers up, don't be upset! We all mum here always support and comfort you. Be a happy twins mum, serena! :-P
