Why must people tell me that I'm a bad mom? What the hell am I doing wrong? My son is one happy baby.. I never do anything to disrespect the title of a mother.. So please, what am I doing wrong? Today I just found out that my own blood, my aunt, was talking about me. I now baby sit her granddaughter which is my cousin's daughter and I guess she was telling my cousin that she didn't want me babysitting her granddaughter because I am not a responsible mother and that I can't take care of my own son... Obviously I'm doing a good job if my cousin keeps bringing her daughter to me. I don't see how I'm a bad mom when I do everything I can for my son. I'm with him 24/7, I never leave his side..... My family used to be all about loving each other. Now that I'm hearing this.. I'm so lost for words.. 😢😢
