I don't even know why my sons mom even bothers picking him up...stop wasting time and just let him live here...she picks him up and keeps him for three days and then she calls and "says he is being bad come get him"or I don't have a baby sitter can just get him? And then wonders why he cries every time he leaves here..you spend zero time with him and expect him to have a connection to you solely off the fact that you gave birth to him...✋🏽 that's not how this parenting thing works smh
