Hello and a kind thank you for spending some time reading this,
Â
My son is about to turn 3 yo in a week!
Â
he is a charming clever healthy happy chap ,he started liking the company of other children about a month ago and frankly speaking i dont see any problem with his development (oh i forgot to add that he is a trilingual! how silly of me - and he started talking about 4 months ago he was saying lots of words beforehand but only during the last 4 months he really got into forming sentences and building his own funny expressions etc)
the thing about my boy is that he have got this strange urge whenever he comes across rails - he just have to rub his cheeks against it,somtimes he will do the same with fences and walls,he also rubes toys against his cheek and smelling them after word and then asking for the toys name ?! is that a toddlerish method of sorting toys by smell?Â
,i was wondering if this sort of behavior is familiar to any of you ? should i worry ,i wasn't giving much thought to this since i thought its his way of sensing textures ?
Â
I would appreciate any help
Â
thanks
