Can i still Join? Alpha Kappa Alpha, Delta Sigma Theta,Sigma Gamma Rho, Zeta Phi Beta?

Hi, i am asking this question because it has been a dream for me to Join Sorority in the NPHC (Delta Sigma Theta,Alpha Kappa Alpha, Sigma Gamma Rho, Zeta Phi Beta) Im not going to tell witch one, but just know i am interested in one of them. I ask this before to members on my campus, but nobody has been able to give me a straight answer. So i just wanted to ask people who may have been in my situation or know members who are. I have a 2 years old son, and he truly a blessing for me, but i don't know how that would look upon members if i am choosing for MIP for me to have a kid. This has been my dream for many years. i just wanted to get some honest options on how members of the NPHC feel about this situation. If you know somebody who has done it or gone through this same situation don't be afraid to answer. i just need to know should i wait and go grad chapter or should go ahead and follow my dream? Thanks in Advance for anybody who can help ;)
