That happened to my little brothers in their toddler years. They were fed a rather impressive amount of gourd similar to pumpkin that was well known as nutritious baby food in the area we were living at the time. I’ll never forget my mom turning to me one random day and asking “Are they looking a bit more… Orange? than usual??” It was quickly sorted out as to why they had become little chubby pumpkins, but that moment was quite priceless.
