Start again - Need technical analysis on constitution

Hi all, I started a thread on this earlier, but it got into another track.

I have been trying to enhance my knowledge of consititutions and really need expert help in commenting on whether my analysis is right/wrong/maybe and what other traits I need to look at.

Based on the profile below, my analysis is Phos.
But after reading Herscu's children's constitution book, I am torn between Phos and Sul. I still lean towards Phos.

Your comments are deeply appreciated. Based on your response, I have some key questions related to constitutional, simillimum and acute remedies

Mentals
=======

* Extremely friendly with everyone - he can approach anyone for a hug
* The daycare he goes to - whenever a parent comes to pick their kid up, he runs to them for a hug
* Very happy kid - loves a laugh and very expressive
* other people who see him always say 'Wow what a friendly cute kid'
* Short tempered - very very happy when you do what he wants, but gets easily upset when things don't go his way
* when he gets upset, he usually throws himself on the floor in a tantrum and cries
* Very easy to get him out of the tantrum - do what he wants, even if it is for 30 seconds
* Alternately, just take his mind away from the 'problem at hand' - like sit him on his play truck and take him
for a ride - do something else to distract him
* Very friendly with others - like to hug them, kids too
* i've noticed he never hits back at others (parents or other kids) - saay if he is pushed by a kid, he will cry
and run for consolation, then forget all about it focussing on something else
* When people see him, the first word that comes to mind is 'cutie and full of life'/
* Likes music - loves to dance to it (fast beat music)


Physicals
==========
* Age 2yrs
* thinner side (Not emaciated by any way)
* Very fine and delicate looks (long eyelashes)
* dimples and cleft on cheeks - people say he is 'going to be a lady killer' when he grows up
* Active kid. When he was a year, I'd say he was hyperactive - never wanted to sit. He is still active
but not hyper - likes sitting down for quite a while watching TV etc
* Had eczema and milk protein allergy (we think the allergy came after vaccination, as we had given him milk
in the first week of birth)
* Eczema has significantly decreased - used to be all over, stomach, wrists, neck , arms. He has what doctors
in the US call 'mild' eczema (compared to really ugly ones I have seen in photos). However, we felt he scratched
a lot. These days, it is only on his leg, and that too, he scratches only when he goes to sleep

Generals
========
* Has a tendency to catch cold/cough easily - mostly due to exposure to cold. When he does catch them,
it settles very easily on his chest (chest rattling and nose congestion)

Food
====
Like I said, he had/has milk protein allergy. Earlier, he was allergic to other things too - like ghee, wheat etc.
We haven't tried milk again but now he is no longer allergic to glucose biscuits, wheat etc.

Likes chicken fingers, noodles, rice. I tried brownie cakes - he does not like them (surprisingly - I thought all
kids will like it). Its not that he dislikes sweets. He loves homeopathic pills (sugar)

OThers
======
* Loves a massage
* Likes taking a bath
