can children even understand the concept of being naughty at this age?? My 14 month olds father keeps telling him off and calling him naughty for the silliest things and its starting to grate on me! believe me I want to bring my gorgeous boy knowing right from wrong and when he does things like pull at the cat I will say to him no. but he isnt naughty. His dad speaks to him like he knows what is doing and is deliberatly ignoring his instruction. The smallest things like throwing a grape from his high chair! Its pissing me off!!!
