if you're preg you aren't supposed to change the liter. but otherwise as long as baby isn't getting into the cat poop there shouldn't be a problem. theres actually been studies done that say that children that grow up in homes w/pets are less likely to have allergies later in life. as long as you make sure the cat doesn't like to hop into the crib b/c it may hop onto the baby than you should be fine. we just made sure that our cat got to explore everything before we brought our first home that way she wasn't curious about something new with the baby already in it (the crib and bassinet at least) and she really just sniffed our dd once and then walked away and still doesn't hang around when our daughter tries to pet her (shes now 3). but shes never once messed with her or tried to bite/scratch her.
the only thing i have heard about babies and cats is that to make sure they can not get in the babys crib, they like the taste of the babys lips and breathe, and can and have suffocated infants on accident
We have had cats before our children were born, during my preganancies and ever since and have had no problems at all. Yes, proper hygiene and proper care of the animals are essential, that should go without saying. The girls look after the cats lovingly and so far have developed no allergies
No, cats aren't bad for babies if you look after babies and cats responsibly..
