I have seen some kids have problems with red tabs, but the one below makes it sound like it's the lower back. It made me think because my daughter has been telling me her back hurts and points to her lower back. This is now our extra seat because she wants her cow seat (ma). Just wondering if this is a problem and what evenflo is doing for it. I'm not even sure I would call them because I have already had to call them twice. Once for my cover getting messed up after I washed it and once because my harness twisted under the seat. I was asking how to fix it, but had to be sent a new seat because it could not be fixed. So just wondering if this is the issue some people have been talking about.
