Re: my carseats expiring
Some sort of harness to booster seat. Kids have to be harnessed here until 40lbs, so probably the graco nautilus. The frontier is kinda overkill for a 5 year old that's so tiny, mine outweighs yours by about 15lbs and is about 6-7 inches taller, and she was only just 5 in October, and she has plenty of room to grow in her nauti. The nauti is less expensive, but still has a good high harness height and weight, and converts to both a good highback and backless booster seat. However, in Canada I don't have some of the options you do in the US, the Maestro only goes to like 47lbs here, and many of the other combination seats you have down there don't exist here.
