Baby Alive Bitsy Burpsy Baby doll toy review of the doll that really throws up, burps and vomits. Gross! DisneyCarToys Sandra and Spiderman feed that baby a bottle and she not only pees her diaper, she also burps and vomits the water back up onto Sandra and Spidey. Luckily, we have a color changing burp clothe to clean up the throw up.
