I think this all is super natural ... for a child of this age.
We only have to natural fears (of falling and certain loud noises) ... watch here >
www.youtube.com... < at about after
sec. 50 ... The women in the interview is a specialist and also says at the end of this video (indirectly) that children do not fear darkness ...
(it's a fear conditioned by the grown ups)
So well, very interesting thread and to be honest ...
I have a gut feeling what the behaviour of your son is about ... especially after you wrote this:
"I have gone into the room while he was in there and tried to sit next to him but it seems like I am bothering him. When he realizes that I'm
there he jumps up and runs off (kind of like he is snapping out of it). And when I get out of the room he runs back into the room and comes out when
he wants to."
"He won't always do it for 30 mins, sometimes 5 somtimes 20 but once he did it up to 30."
My nephew showed exactly the same behaviour in this age around 2 and he was a late bloomer too bc he was a preterm delivery. Compared to my niece who
is 3 years senior to him, he also started to talk properly and in full sentences much later. But seeing and caring for the children of many friends
and family members, it's absolutely normal that boys do start talking later ...
(The second son of friends didn't talk much for the first 6 years and was very bad in reading at school. The parents did put totally trust that it
his way of development and put him on a Montessori School were children are given the surrounding of making their own decisions (what to learn and
where to participate) very early.
After several months at school and teachers worrying about his reading ability ... from one day to another he started to read complete articles out of
the papers
So he just was lazy, observed, safed his energy and had this 'coming out' when he was ready to read!)
But back to your 2 year old ...
Errrmmmmmmm ... could it be ... ??? *LOL* That he is doing 'his business' ??? I mean filling his diapers/nappies.
My nephew was and is also very active but when he had to do his poo-poo he was disappearing out of the blue for several minutes.
I once found him behind a curtain, standing there stiff, numb and concentrated and with a highly red face full of pressure, if you know what I mean.
It was all very funny this time around because he (and also my niece) had the tendency to hide into closets, dark tight corners, bigger paper cartons,
under the bed and bigger paper cartons ... not just to make their business.
When he first disappeared my family started a bit to panic and run through the house searching and shouting his name. I started to look for him/her
silently and also observed once my niece in her early years talking to her imaginary friends. Her behaviour really was like someone was standing in
front of her; I was just not able to see that friend. Later on I even asked her and she started to talk about her friends. They were 3 of them and
also had names I still know. She also painted them ...
My nephew also sometimes fell asleep in the (dark) place he was looking for shelter, to do his poo or just to take a rest. Once my sister was close to
call the police bc the boy had suddenly disappeard for more then one hour, they had looked for him in every corner of the house and even asked the
neighbours. He was lieing and sleeping peacefully in the backmost corner under his parents bed, where the flashlight didn't reach ... We have mad
several pictures of him were he fell asleep in places you normaly do not sleep, just bc we were not able to understand his signs and rhythm. When he
made several yawns, you had just about 20 minutes to feed him and change clothes for bed. Otherwise he started to look for a cozy place or slept were
he just was ...
Hope this helps!
