Re: car seat options for a tall toddler?
Assuming for the moment that you do NOT live in the US and therefore Canadian car seats are really your best bet...
What is your new budget for a car seat? Seats are all pretty expensive in Canada. Would this be an option? :
The reason I'm asking about it is because it has harness covers which might help prevent the squirming-out problem. I know how frustrating that is because I have a squirm-out-of-the-straps toddler myself.
