Another individual data point with a PG kiddo who is now a teen-- she learned colors so young that I'm not sure when it happened, and knew letters that young, as well (including phonemes for all of them by 20-24mo), but didn't read-read until she was nearly five.
Like Blackcat's kids, she had one-to-one correspondence very early-- definitely before she was verbal enough for us to KNOW that she had it. But looking back, she understood object permanence from a few
weeks old (peekaboo and 'hide the object' games were just strange and not entertaining to her once she was about 2mo), and that is a related thing, apparently. She was certainly counting objects up to 5-10 by the time she was 12-15mo when she began demonstrating the skill verbally, at least on occasion.
She was another one that it's hard to judge precisely when she possessed the skill or developed it, because she was such a black box. Skills came out of nowhere, and generally with total mastery, so I understand exactly what Marnie is saying there.
Shapes definitely came later than colors and numbers/counting for her. Not sure that it means much, as she definitely has v-s ability to spare, but also has that mathy abstract thinking.
I also have to wonder how much educational programming/materials your younger child has been exposed to via the elder sibling-- DD really lacked a lot of exposure to certain concepts until she got seriously ill at 15mo and we began allowing (okay-- encouraging, really, because she had to stay quiet and rest for about 90% of her waking hours) educational television and videos.
Once she saw things like Sesame Street, those schooly things took off like they were headed out of orbit.
On the other hand, we know an agemate of DD's that would have looked
more verbal than she did when the two of them were 18-24mo. In fact, they were in childcare together and were twin-like in many ways-- both VERY verbal for age, very bright, and highly socialized. The other child, let's call her Z, is someone that we kept (kinda) in touch with when they moved away for 3y on sabbatical-- we ran into them again regularly when the two girls were 8yo.
The difference between them at
that age was downright staggering. Z is what I'd term "bright,
maybe MG." It was shocking-- I recall being baffled and wondering "What on earth
happened to Z??"
She looked quite gifted alongside of DD when they were both toddlers and preschoolers, mind. Looking at the two of them at 2yo, I actually recall SAYING to my DH that Z was "very much brighter" than our DD-- and both children were radically different looking than all of their other peers in that setting.
That's a difference that I chalk up to "enriched home environment" which
both children possessed in abundance (all parents terminally-degreed, similar household income/patterns). The difference at 8yo, however, was in LOG-- and as noted, it was downright staggering to me.
Enrichment alone (and he'd definitely have that, having a PG older sib)
can appear to be a higher LOG at this age.
They don't
all even out, I guess that is what I'm saying-- but at the young ages, it's really tough to know exactly what is massive enrichment (not saying that this is
wrong by ANY means)-- just that this can result in a picture which is nearly indistinguishable from a fairly high level of giftedness in toddlers and preschoolers, if one is just looking (casually) at achievement or milestones rather than rate of acquisition or other more direct 'tells' of high cognitive ability.
If I try to recall what the other girl was like at that age, and focus on what was different about them from other children, and what differentiated the two of THEM from one another?
DD was more--
regulated. That is, she was less verbal (mostly), but she also didn't chatter aimlessly when she DID talk. She was very attuned to her surroundings-- eerily aware in a way that Z was not. Aware of the sensory detail, yes, but also far, far FAR more attuned to the adults and other children around her. Both girls were moving out of parallel play into interactive play, but DD was well and truly already THERE.
It wasn't so much differences in skills-- it was a certain sense of self-awareness that differed.
Also, the
rate at which each child tried/failed/mastered intellectual tasks was different, now that I look back on the two of them. DD didn't tolerate failure-- she would back completely off and STOP rather than fail-fail-fail at something. It was like she took two steps back and just
observed and thought deeply. It was quite striking.
Some of that could well be personality, but I don't think it's all of it, as the two girls are both pro-social and highly introverted. I don't really know what MG or HG development looks like, and I do know that if you've seen one PG developmental arc, you've seen one-- but this might be food for thought.
