Hi Jim here ,if you have two sockets that are leaking a green dye , if this is so then you have a liquid of some sort leaking into the sockets ,as regards the other two sockets if they are sparking when you pull the plugs out then they must be the un switched type, which are illeagle to use in a childs bedroom as they are permanently live and a child could easily poke something into them and be severly injured , for the sake of the children and any other person in the house have all the sockets replaced by a fully quaulified electrician , and have the leaking seen to REMEMBER electricity , does not wait for you !!!!!
