I find myself constantly referring to these charts when I read books or look at baby products because there are often references to the appropriate weight/height range for something like an infant carseat or clothing sizes. So, here they are in case you find them useful.
Disclaimer: I know this is a SUPER oversimplified chart that doesn’t take into account many important factors, but it is useful for things like estimating how long your carseat will last. I like this chart because it’s user friendly. The CDC and WHO charts are much more nuanced, but a pain to interpret each time.
Also, here’s a handy calculator to calculate your kid’s growth percentile.
