Query: So dissapointed!

I fell in love with the chair before our son was born. I quickly learned that the plushy fleece is just a sell for the parents. The worst feature - the vibration has a self timer on it and it shuts off after 10 minutes. There is no override for this! So, before my son had even fallen asleep, the vibration would stop and he'd wake up! Another bad feature - the safety straps are so short! If he is swaddled or in a fleece sleeper, I can't even begin to latch them. He's only 2 months old! I wish we hadn't wasted the money on this item and plan to contact Fisher Price about it!
