Grandson chewers his shirt & also very rarely walks mostly runs in the house. Can never remember what he ate from 1 day ago . He is very academic excels in school .. he also sticks his tongue out a lot to the point that he gets a rash around his mouth .. very well manned & loving .. my son took custody of him when he was 4 as his mother was not responsible etc she is the daughter of my sons wife from 1 st marriage . He use to cry a lot & has scares on his tongue from biting from crying . My daughter in law says these issues are just quirks I don t think so . Hope to hear from you .Thank you , Victoria Rawlins
