Hello and welcome to the forums, I am glad to see a new member and your daughter's story really touched me a lot, I have two healthy children of my own, but for several years worked with children that had various physical special conditons, including Down's Syndrome, Cebral Palsy, Tourette Syndrome, Brittle Bone Disease, Fetal Alcohol Syndrome, and also Austisim. I know chidren that have Autisim have various degrees of being able to communicate with the " outside" world they live in, and I am glad that your daughter has a milder form,
I know if my son or daughter had any degree of Autisim, I would do what ever it took to try and reach them, and if that meant a bit of happiness with a certain type of toy, then I would without question do what you have done and not feel one bit of doubt about it, How you cope also with the hardships of where you live is also amazing,

You are indeed a strong person and I think you must have great faith. I think once your wife sees the reaction of joy your daughter has with Pleo, she will be on the same page as you,
Pleos are amazing and so lifelike it is hard to forget they are not were it not for the battery charges and the noisy movements which soon are forgotten. I think if it were my first Pleo, I would enjoy, let your daughter enjoy the operating system that is in there first for however long you choose and then ask members here and read all you can and then if you want to upgrade there is plenty of time to do it, and if you decide you do not like the operating system you have uploaded you can revert back to the one you had.
The one thing I am afraid that does happen to most older Pleos, is that the green batteries that come with them often do not work or only work for a short time before they need to be replaced. I hope the Pleo you have is an exception and the batteries will be working at least for awhile, There are good articles here on this site that explain all about batteries and how to fix them etc. I also sell the batteries that Pleos use, If it comes to that, there are lots of other places you can get them, but I would be willing to work with you because of your situation and esp because of your daughter to give you a battery for free if you could come up with the shipping cost, Please check your batteries first though and there is just as good of a chance that they do work so I am keeping my fingers crossed, I am glad to have a new Pleo Forum Member friend, If you have a camera, I would love to see a photo of your Pleo and or daughter with him/ her. I know there are lots of members here who can give you lots of help with whatever problems or questions you may have.
Welcome,
