she is 3yrs 8 months and she has always been on the challenging side but lately she has been terrible, blowing raspberries in my face when im telling her off, hitting me and daddy, running off on te road when we tell her to stay by us just generally naughty and no matter how much I tell her off or at extremes smack her it makes no difference. I work full time and when I get home I just wanna have fun and cuddle and play not scream and shout and put her to bed.
