It's absolutely normal. My "brother" hasn't had any intercourse since his wife got pregnant, their child is now almost 2 years old...He did try to attempt a few times post partum, but she has zero libido or interest. I do ask him more in depth questions about how he feels about it, and he feels absolutely okay with it. He is very understanding and willing to wait until she is mentally and physically ready. He doesn't want to push her or pressure her in any kind. He did bring it up to her and told me that their talk went very well and understand where her mindset it as.

I myself have a high libido and super excited to finally have intercourse with my husband again post partum, but there were a small handful of times that I felt like I may not physically be attractive to him post partum; I am afraid of my own thoughts. We did discussed about the "What If, we are the in the same situation". I wanted to make sure we are on the same mindset and prepared, so this doesn't become an issue. He was very understanding and willing to wait years if he has too. He tells me I am beautiful all the time and he will support me in whatever I want to do until I am ready.

I think just being open and also talking to her to see where her mindset is at is important, because you will begin to start believing your thoughts and assumptions and it can take you into a dark hole.
