Terrible maids with kids in the Marina

I quite often go down to the fountains in the Marina area and the play area in the Emaar 6 buildings with my daughter and have seen some pretty terrible maids looking after kids. There's the big, sri-lankan lady with the crazy eyes who a few people have seen beating the baby she looks after and forcefeeding him food while he cries and vomits. There's the african maid who pushes around the baby she looks after underneath my balcony, round and round while the baby screams and she pays him no attention - all the while she talks on the phone. In fact both those maids are always on the phone and never take the babies out of the pram. Then there's a little girl called India who I always see tied up in her pram even though she's a toddler. The other day I was standing outside spinneys and saw her maid shout at her so violently and then scream "shut up! shut up!" while India cried - just so she could continue talking to her friend. Then at one point she raised her hand in the air as if to beat her and only then did her friend point out that I was looking at them. She just brought down her hand looked away and kept talking to her friend. The next day I saw India again, and once again she was tied up in her pram, once again with tears in her eyes while her maid spoke to another maid. India turned and looked at me with such sad eyes like something inside of her had broken. It really affected me. I thought, she cant speak for herself but someone should. I always think no matter how uncomfortable it may be if I ever saw the parents of these kids out with their children I would tell them about the behaviour of their maids. But I never see the parents. I just see the kids day in day out with the people hired to look after them. I do think though that if you leave your children in charge with a maid all day then you should pop-in from time to time unannounced, or go spy on them when they are out and about, just to make sure they are giving your kids the best care that they deserve. It's the least you can do when you've hired someone to look after the most precious being to you. I also think, if the maids are acting like this in public, what are they doing in private?
