I just found this article connecting Rickets, Epilepsy and the Lymphatic constitution unfortunately not from homeopathy.
But this is so interesting because Ancient has a rickety frame, probably infantile rickets, and he has a kind of puffing breath at times which is apparently from a thymus enlargement according to the article. It's also supposed to be connected to an enlarged spleen. Epilepsy develops from a combination of the three.
I could try to do something with this knowledge. He's stagnated, with no strength to walk and falls at every attempt.
