I worry about your dd being so small with no 5-pt harness, but of course you're the only one who truly knows your situation
There is a common belief harnessing is safer than boosters for older kids but it's simply not true. People working seriously and professionally with car seats know this very well.
Chickybiddy's comments sums everything up very well (thanks for the nice summary)
|There is absolutely no evidence that children who are able to use a booster properly (this includes physical and developmental maturity as well as correct fit and use) are safer harnessed than boostered. There is some non-conclusive evidence that 5-point harnesses protect better in certain crashes, and some non-conclusive evidence that boosters and shoulder/lap belts protect better in certain crashes, but overall, they are both extremely safe choices when used correctly and again, there is no evidence that one is better than the other.
Belt fit is important in boosters. Age is more important than size since skeleton mature with age. Weight has little to do with safety. A 35 lbs 4 year old is just as safe as a 50 lbs 4 year old as long as belt fit is good.
