Cat's behaviour when baby cries

[EstRusMum]

Hi all. I am pregnant and have a female spayed cat. She has never had kittens and is really crazy youngster. She is about 9 months old at the moment. I'm due in 6 weeks and thought to try and get her used to baby cry by playing video from youtube. Now, when I started playing it, she came over and bit my hand. I paused it, she walked away. I played it again, she attacked my OH feet - biting, clawing and holding on quite strong.
It's not unusual for her to bite or claw people(like I said - she is crazy) but this time it was different. It wasn't playful, as usual.
I was wondering, does anyone knows what it was and whether I should be worried? I mean, I love this cat, but if she will start biting the baby each time she cries, I do need to find a solution.
Thank you

She is still a kitten, kittens do that. I wouldnt worry

Baby cries have been found to be very similar in pitch to kitten cries and so cats may react. Get your cat used to baby noises by playing them up to baby arriving, exactly as you're doing, and give cat somewhere they can get away if feeling stressed (eg they have their own room, corner etc where baby is not). Cat will get used to it but you may need to supervise at first
