I have seen some people complain how the OPLA writers omitted that everyone was watching over Nami when she was sick because of Sanji's line and, I have to admit, I was sorta thinking similar too (I think I do have a 'sheep mentality' or whatever you wanna call it)...
Until you remember Sora. Plus, the fact that in OPLA (thanks to the power of foresight), Sanji shares his experience about his mother.
So, it kinda makes sense for Sanji to be the one who had the most time watching over Nami. He's scared. He's worried.
Not to mention that he obviously has experience with caretaking. At least compared to the others. If I had to pick, it would be Sanji.
That isn't to say that the others didn't watch over her. Realistically, Sanji wasn't there 'the whole time' for those four days. I'd wager that there were moments Sanji had to leave the room to cook, but not before making sure someone is there with Nami. Hell, the others probably had to force him out so he could sleep and they take turns keeping watch.
Plus...it's possible the others...don't feel comfortable seeing Nami (someone strong and independent) so sick and weak...
Like Usopp. His mom died to illness too...
It's not that no one cares...
They care so much that they are scared and aren't sure what to do.
