How do you scrape paint off of a wall?
Answers:
Latex paints tend to stick well to themselves, so I'm guessing that the wall was originally painted with an alkyd paint, and then painted over without propper prepping. Each coat of paint shrinks as it dries, putting tension on the previous coat. With each coat this tension builds up until it finally pops loose from the point of weakest adhesion. All of this could have been avoided if the layer of alkyd paint had been sanded and primed. Sanding is necesary to get adhesion to alkyd paint. This is not mentioned on the labels for most primers because people hate sanding and so if they were told that they need to sand, people would instead buy a product which doesn't tell them they need to sand.
Most of the paint should be removable with wall-paper shavers. There are razor-blade style paper shavers, but these are so sharp that you will end up gouging the wall a lot. You'd probably have better luck with the style which looks like a 4 inch wide thin putty knife with a sharpenned leading edge. These are much easier to control, and should work well for most of the paint removal. A standard razorblade scraper should work for most of the rest. Also the style of paint scraper that you pull could be useful.
Anything that is left after all that is probably adhering and not a problem. So sand the wall, prime it, and skim over the edges of the paint which didn't come off (as well as the places where you gouged the wall with the scrapers) with patching. Personally, I prefer the type of patching that comes dry and and you add water to, such as Easysand 20 (the number indicates how many minutes you have before the binding agents harden to the point that it is no longer spreadable). These products tend to adhere better and dry stronger than pre-mixed patching materials. Sand the patching, prime the patching, and the wall is ready to paint.

It would help to know if the wall is>>>>>Wood? Dry wall etc. Give all of the details and I'm certain you will get a great answer to your question.
Thats a tough one lucky...You can buy a citrus based stripper which is much safer than the chemical strippers but you still will have to have good ventilation and you dont want the kids to touch it...If you try to scrape it you will never get it all off evenly and you will probably have a worse looking mess than you have right now...If your feeling ambitious and you want a really nice looking room you can buy sheetrock that is only 1/4 inches thick and put it over the walls you have now...
Why don't you just primer it and paint over with the new color you want? It would be a lot less hassle.
you will mostlikely have to buy stripper to do that, but you can always ask someone at home depot
