Need advice!

Ok so my best friend of almost 10 years doesn't seem too interested in my one year old son. /: it makes me mad. I don't really know how to approach her about it because she doesn't care for kids or want any. When I first had him she took a few days to even congratulate me (take in mind I gave birth across the country but still) it hurt my feelings bad. I told her about it and we lost contact for a few months after that. We recently getting back really close and she still just doesn't really ask about him or anything. What should I say or do? If anything. It just bothers me because I'm obsessed with my son and she doesn't care at all really.
