^^ yes ^^
I had a 2 month old on the seat! They made me wake her up and said she had to be out of the carrier, which I was okay with. But when I asked the issue, they said whiplash. Not that I couldn't hold her! It wasn't until we were in the car that they told me she had to be sitting. It was so jerky. I felt terrible that I didn't just say forget it and get back out. I didn't want to hold up the ride, but I should have!
I think the baby being in a carrier, especially the ones that face in, would do better preventing whiplash! Skip this ride until the baby can sit well on the seat.
