Cryptic messages from mother in law

My husbands grandad is not very well - well into his nineties and so expected but still very sad obviously. My mother in law keeps sending cryptic messages on our WhatsApp group saying things like “grandad not doing well” “grandad not good” and I just think it’s really not helpful for my husband as it makes him worry but he doesn’t get the detail of what is going on. So then he will go and visit and his grandad is actually fine. Or if he calls her she’s like why are you calling me I’ve already updated you. I was almost on the point of saying something tonight just to say please send more detail on how he is because my husband naturally jumps to think he is about to pass away. I’ve held my tongue so far as she’s obviously sad but she does this all the time with other things too. We live about an hour from them so not too far but also not super easy to just pop over and see what is going on now we have our little one. Any advice?!
