Think I need a new car seat for my little so give me all the convertible car seat recommendations.

We currently have the Graco extend to fit and I honestly hate it. It is IMPOSSIBLE to tighten the harness and I don’t feel like she is safe in it. I’ve only used it a few times since installing it but I am highly considering selling it since it’s impossible for me to use it and buying something different (of course I bought it on Black Friday 2020 shortly after we found out we were expecting so I can’t return it…) I bought it because I had seen so many people rave about it and it is most definitely now on my list of baby products I regret purchasing.
