cat vs newborn vs in laws

So my in laws has always been against my kitty. I have a 9mths old siamese kitty. Shower every other week, indoor cat, goes supervised outdoor (corridor) walking once a mth. But spend most of her time running, eating and sleeping like what cats do. Have to wipe her butt everytime she poops. My mil has been urging me to get rid my kitty even when we dont stay under 1 roof. She keeps saying that kitty will bite and scratch baby and cat furs will make baby have asthma etc etc. But i was brought up with cats, so im super attached to cats. Even told my hub that i need a cat once we move in together back then. And he agreed. I talk to hub abt this mil vs cat situation but he keeps saying that his mum is just fooling ard. Mil even talk to my mum to convince me to get rid of kitty. How or what or idk how to deal with this. And im due in 2 weeks time.
