Pregnancy gender question

Keneshia • Mommy to be, 22 years old
"Old folks saying" So my boyfriend has two niece and they love me to death. Before I knew I was pregnant the 2 year old would never leave my side.  She always sleep with me and always close to me. I heard a girl is like that when you are going to have a boy. And now that I know I am pregnant she is still the same way don't want nobody to hold her but me and everything like I'm her mom. And also we plan on telling our parents today on Father's day what do you all think.?
