so my little Russian has favored lettuces of all kinds! i have tried multiple times to get him to eat some dandelions and some other weeds, i have even tried to hide them under some romaine (his favorite). should i try some tough love and only offer weeds and only limit his lettuce intake? or is it ok for him to just eat a wide variety of lettuce greens from the store? i got him to eat a dandelion leaf once, he made an awful face and gagged it down... what should i do? he loves red & green leaf lettuce, romaine, kale, mustard & collards, and much more.
