I got a stage 2 seat when LO was around 9 months but I hate it and see it is now possible to get carseats suitable from about 9 months up to 12 years. Essentially they are a highback booster seat but have an integral harness for use until child is older.
Anyone have one and have a view on them. The 2nd stage one we have at the moment is a big clunky thing that is difficult to get LO in and out of, especially when she doesn't want to get it!
