For reasons he might be with/in the CMC, there are many avenues to attack the problem from Perhaps he has a prior
relationship with one of the player characters (Friendship, infatuation, familial ties, employed as a guardian/assistant by a parent) and simply tags along to help them, or he might be a hanger-on, kept around and liked for his draconic abilities, in the end it is up to you
The way I look at it, the 'Hatchling' dragons are like Spike, wingless chubby little guys, good for fine dexterity (Hands FTW) and being a tough little dragon.
The next growth stage 'Drake' is akin to the dragons Spike met on his quest, winged and aged into their teenage years (30-40 by my head-canon)
So no, your little guy onto have his wings yet sorry...
Though something related to that might be a good idea for an adventure later on *Opens .txt file and types a few lines*
And now I can't but love you.
