In case your kid is rocking an older exersaucer and you're a bad mother, please note...
"The plastic covering on the soft block towers can detach, posing a choking hazard to infants. Graco has received 137 reports of infants mouthing and chewing pieces of the plastic film covering, some of whom required medical attention. Serious incident reports include 32 infants who gagged and 49 who choked on the plastic covering."
Oh, there was choking, there was gagging, there was throwing up... and there was the piece of plastic! So, warning for others. If this is your exersaucer, Graco will send a replacement part. There are more details about model numbers and stuff on gracobaby.com. Here's a photo of the death trap in question...
