As we also got twins (a boy and a girl) of the same age, I think I have to share some of my experience and feeling with you. I have hired one Indo maid to take care of the twins only because of the limited space of my flat. At beginning, I also worry that my maid cannot handle 2 kids. During the first 3 months, I have hired a part time local helper to do all the house work and my maid is required to take care of my babies only. It is already very busy for her to look after 2 new born. Starting from the 4th month, I do not employ and local helper any more but my mother-in-law will come everyday (Mon to Fri only) and she will prepare the lunch for my maid and herself and dinner for us. My maid is only responsible to look after the bb and do cleaning work. As at now, I think the arrangement quite work. But of course the most important thing is your maid is good at taking care of bb and likes bb. In your case, I think you should serious consider whether you should fire the maids and find replacement, who are not friends and like babies. A good and helpful agent is also very important. Have you reported the case to the agent? According to my agent, if they know the maid is no good, they will not help her to find another employer again when the current contract expire. But my agent is only a small firm, not a famous one. Hope you can solve your problem soon.
