Cats and babies

Hey ladies, wondering I have a 7 month old and I also have a very loving cat who I’ve kept out of our room ( baby sleeps in his crib in our room) for the whole 7 months. I know it’s a myth mostly about cats suffocating infants. But when would it be sate to be able to let my cat come in our room as well. Keeping our door open at night. I of course would rather be safe than sorry. But wondering how other cat owners handled it? Thanks !
