My two ds are driving me crazy.I live alone with them and they are two and a half and nearly five.youngest is bright and fearless, often hits me and just laughs when told off.eldest is scarily bright, obsessive in his interests (any thing electrical but especially vacuum cleaners) can be great but is mentally challenging and just keeps trying to reset all the rules and again does not respond to telling off..I end up absolutely shouting my head off, it makes my head hurt, does get their attention but I think its clear that I've then lost control.smacking does not work and I just feel mean after. The threat of their Dad works for the older one (which is one if the reasons that we could not agree on and he does not live here)...what do I do?I feel desperate sometimes.I get so stressed I break out in a sweat! I work almost full time but I want to enjoy the weekends more with them.do I sound awful?
