At what age or size did your child no longer find the Chicco Nextfit comfortable? We have an extra one in my husbands car that I figured either child could use (5 year old and almost 3, both somewhat short- Obviously I would adjust the headrest/ straps between the two kids).

I just reinstalled it with the seatbelt since my older daughter has outgrown the Latch weight limit, and the headrest seemed like it was at the max height for her, without a ton of room to grow. She said it wasn’t as comfortable as her regular seat which is a britax frontier combination seat (harnessed).

Even though she is technically within the height and weight limits, I’m wondering if it’s getting uncomfortable or she’s just being difficult. I’m not opposed to getting a high back booster to keep in his car since we only use his car for quick trips around town anyway.

We moved her to the combo seat when little sis needed the convertible so I have no idea when she would actually outgrow it.
