Can anyone give me some advice im new here and my 20 month old son has started calling me by my first name instead of mum. He calls his dad daddy,nana nana his brothers by there name but me amanda. Its really bothering me as hes with me all the time n has been since birth. Yet suddenly im amanda and not mum anymore. I dont know how to get him to stop and everyone but me thinks its quite amusing can anyone give me any advice. Is this normal i have 4 older kids and i dont recall them ever calling me by my 1st name.
