My grandma is like that - nobody she knows personally has ever had xyz happen to their babies thus it is a marketing tactic to make peopr buy more stuff.
I have my mums bassinet though (my brothers & mine), it's been kept in perfect condition, it's 30 years old and lovely, including the bassinet covers and sheets my mum hand sewed in hospital pregnant with her first baby (mum was in hospital 6 weeks and baby didn't make it home so it's very precious)
I'd still look. If there's anything small and sentimental you can use if it would mean something to your mil.but absolutely don't feel obliged to compromise babies safety.
