A lot of the developmental questions on this site are about Language, but I'm less anxious about missing language milestones than I am about other potential developmental milestones that I may be unaware of, for example "cognitive", "mobility", etc.
Just off the top of my head, I thought of:
- Emotional (sometimes this is combined with #2)
- Physical (which includes mobility but mostly fine and gross motor skills in general)
- Oral (This doesn't just include language, but also eating and the ability to properly manipulate the mouth/tongue which will influence language development)
Technically, 5 and 6 aren't true milestones, but from my own experience I truly believe that these two things are important enough to warrant a separate point. Before we got C's new RGP lenses, she was starting to get well behind on her development, but as soon as we changed she began hitting milestones like crazy and is completely caught up. The same is true with her language development. We had a really hard time with ear infections for a few months, and a couple of weeks after we had tubes put in her vocabulary just exploded. I can't prove that the tubes were the primary reason for that...it might just be that she was due for a vocab explosion anyway, but I don't believe it's a coincidence. I've listed a couple of websites below with some good general milestones (but it seems like every website has a different list).
- Developmental Milestones Chart (newborn through adolescence)
- Visual development An interesting aside to this that I believe was pointed out to us by our pediatric ophthalmologist is that children's peripheral vision isn't fully formed until they're 10 years old! Ten! Takes on a whole new meaning when your child is fully mobile and sprinting for a parking lot with an on-coming car!
