Not Friends after the baby comes?

Has anyone ever experienced something where when their friend had their first child and basically abandoned everyone and everything? I don't know but I feel this is how my formed may end up being. Of course she deserves to spend time with her baby and some things may come 2nd but I feel she may end up feeling like she can't even leave her home for a second to even go to the store. I feel she'll never speak to those of us who are her friends and family for quite a while. I don't know I just want her to feel like the only thing she's allowed to focus on is her child. That and I'm worried for her to fall into post partum etc
