Ok so we have always had a van up until now. We just bought an SUV and now I can't just move the van captains seat forward to make it more secure rear facing. I don't know how normal it is for the seat to be able to move up and down. It doesn't move side to side really...well way more then it did in the van. It is as secure and tight as it will get and I hate how it moves. Now my daughters nautilus is so tight its like its glued but its forward facing and has the top tether attached as well...my question is even not tight tight is my two year and eight month old still safer then a rock solid tight forward facing. It drives me nuts because my daughter was rear facing til four and I want to do it again but this looseness is a huge worry to me.
