@Sams Mom: The harness height for the extend2fit is about 17.5 inches. The nautilus harness height is about 18.25. The myfit harness height is about 19.5. Average torso growth is about on inch a year - so if he is truly maxing out the extend2fit he would only have a little less than year or so in the nautilus versus two years or so in the myfit. And the 4ever harness height is about 18 inches.

That said I'm a little surprised at his stats that he is outgrowing the harness of the extend2fit. My DD is about 46 inches and has a seated torso height of 17.25-17.5. I would measure his seated torso height first to get a better idea.

The chicco is much narrower and will last longer than the nautilus. But they are both good seats. You could also look at the Britax pioneer.

@Sams Mom: I would definitely check to see if the extend2fit has one more click up. Sometimes when it is installed it can be hard to get the last click. There should be 10 headrest positions, so you could start at the bottom and count the clicks up. If he really is outgrowing i would probably not get another nautilus just because it wouldn't give him much more time.

I still would check his torso height. Have him sit criss cross on the floor against a wall and measure from the floor to the top of his shoulders.

I don't know how often the baby will be with the babysitter but you could consider having her do a baseless install of the infant seat. Probably a pain if she will have baby a lot, but if it's just occasionally it could work.

@Sams Mom: the nautilus 80 has a higher standing height limit but the harness height is the same.

I would say have your husband try to do baseless if he will have the baby the least. They use the infant seat for such a short time.

Following ... almost the same situation here haha, same carseats
