As a matter of fact, within Japanese native animation industry, Pokemon Anime is deemed officially as kodomo anime.
However, personally within my eyes and brain, IMO Pokemon Anime specifically the current XY saga, it feels too shounen-like to be consider as a kodomo anime.
In Japan, kodomo anime is differ from shounen anime in a few aspects, as they are made with the mindset of targeted to and intended to be watch by pre-schooler children. 1) Line-art of the animation are simple, meaning it will not take too much time or effort for animator to draw a picture, hence there is an aesthetics simplicity in its graphics, which shall be ease to watch for the eyes of the young. 2) Colours of high contrast are often being used, which it shall stands out more in the eyes of the young compare to pictures consists mainly of colours of low contrast. 3) Generically no complicated plot nor sophisticated characters, as their actions and reactions need to be simple enough to be understand by young children. Overall world-building thus are also often very shallow, and often lacking characters dynamics. 4) The most important part. Despite that it may not have complicated plot nor sophisticated characters, it needs to function as a form of emotional eduction teaching children morals and ethics of the world and nourish their sentiment, hence being an edutainment. Because of that, good and evil within kodomo anime is plain and simple being strictly black and white, don't even hope for any much grey area in between. 5) No violence and no bleeding, no killing and no emotional "vanishing", no boots and butts and panties, no fan services nor tiny sexual innuendo, no feeling of lethal danger nor sense of critical emergency. Combining with 4), the conflicts and battle within kodomo anime will thus be heavily tone down where a fight is not a fight, but competition or "correcting the evilness", no one will hurt at the end of the day.
Regardless of the themes and genre and quality of the animation and sound/VA, because Pokemon Anime matches with all the criteria as describe in above, it is unfortunately a kodomo anime, whether one dislike such categorizing or not.
Yet, as I had said in the beginning, personally IMO, Pokemon Anime especially in the XY saga, it is too shounen-like to be deemed as a kodomo anime.
It is due to its animation quality and sound/VA quality, also the intensity of battles within this series, and ME Special OVA. For a show of intended to be watch just by the pre-schooler young children, IMO it felt like a deplorable waste of budget on upgrading things that are from the very beginning not needed in kodomo anime. If TPCi was indeed wanting to cater the Pokemon Anime more into the shounen demographic, then in fact it needs a complete overhaul and revamp.
Edit: It is quite interesting seeing quite many fans deemed Pokemon Anime as a shounen anime rather than kodomo anime. So that is the "image" Pokemon Anime given out to the public. I see Pokemon Anime is certainly incompetent in its own publicity marketing.
