Car Advice

Hi I have some questions on vehicles. My father in law brought it to my husband and I’s attention that the suspension on two of our cars may not be safe for the babies soft spot after birth.I’m due to deliver 11/2022 for context. We currently own a Subaru WRX STI and Focus ST both manual they have plenty of space but the suspension is in the question. We also have a Pontiac G6 but the starter went out which will be fixed in a couple of weeks. Yet in the event we need to drive one of the other cars is it ok to have the baby in it for a couple doctors visits?
