I had one for DD and recently got a new cover for this baby. We LOVED it and it really saved us a lot of sleepless nights. DD hated her crib and always wanted to be held. She would sleep for only a few hours at a time and spit up a lot. This was such a lifesaver!!!!!!
The thing is... this company spent a lot of time coming up with a product that was SAFER for babies to sleep than being put into a car seat or propped up by pillows. Babies with reflux or other health issues can't sleep flat so parents look for ways to soothe baby, anything just to get some sleep.
It isn't PERFECT but it is BETTER than a lot of other options.
I feel bad for the family's loss but I don't think it is the company's fault.
