i dont really get what you meant but i hope my opinion helped.
there are four different toddlers, mizutamatchi, mohitamatchi, puchitchi and harutchi.
for mizutamatchi, it will only be in the meme family.
for mohitamachi, it will be in either the kuchi or meme family.
for puchitchi, it will be in either the mame or meme family.
for harutchi, it will only be in the mame family.
note that every toddlers will change into a universal character if you neglected it.
