I just got an 07' Honda CRV, I absolutely love it...and I am ok with the install I got with DS's MA(I did take the head rest off, that's ok right?). Here's the thing, DH wants to get another seat so we aren't playing switcharoo every time he takes DS somewhere in his car. What seat should we get? DS is 4 1/2, about 43 inches and usually about 38 lbs. He is definitely not a tall guy, he is on the 2nd to top slot on his MA. DH wants to get a seat he can use for a while but isn't necessarily expensive as we won't need it forever...he knows and agrees that the plan is to keep DS harnessed as long as possible. So our dilemma is do we get a seat that turns into a booster eventually or save the money and buy something that just has a high harness weight and height and buy a nice booster later(he has this idea in his head that it might be cheaper that way). So, we are confused. Please help.
