Toddler with ec symptoms

Hey guys. I've posted once before on this site when I was pregnant and I was so worried about passing on ec to my son. He is now 20 months and is showing signs of ec :( he started to get dry lips when he was around 1 and his doctor said it could be from dehydration. He loves water so much then and now so I knew it couldn't be that but now his triangle part on his lips peels all the time, turns white when wet and he has started to pick at it with his fingers and even with his mouth i try so hard to distract him from picking at it but I can just see it bothers him feeling the dry peeling skin. So far it hasn't happened on any other part of his lips. Also it's not so common for toddlers to have dry lips.
I don't remember if I explained my situation in my old post but I still have ec and am no where near curing it. My lips look mostly normal their still bright pink when i wipe the skin off every day but I am full of anxiety and insecurity i just cannot leave them alone and let them build up. I've always tried to believe if I didn't come onto this site and didn't stress or think about them all the time that it would help but now possibly seeing it on my son I would really love any tips to prevent it from getting worse. Please and thank you Tweet
