I have been looking at buying DD a toddler car seat soon so that the new baby can have her car seat. ATM, we have a SnS 'Guardian' and 'Safekeeper'. We only have a medium sedan car and would rather not have to buy a new car just yet if we can avoid it, so we are trying to find a seat that will fit into the back without too much trouble! So it needs to be a compact seat. (I will look at getting the baby and DS new compact seats if necessary, but thought getting DD one would be a cheaper option for now!) I would like it to still have the harness in it because DD (who is 3 1/4yrs) is still only just 14 (ish)kg. I did wanted to get a SnS 'Maxi rider' but looking at reviews it says that it is quite wide. I want a seat that will last her til she's at least about 5 or so, so I don't have to buy another really exxy booster for her later. And preferably nothing costing over about $2-300.

Any suggestions??
