U be told these are normal for a toddle. My boy as siblings with autism and he worse then they was and are peds say everything said been seen and documented is very normal 4 a nearly 18 month old can't help comparing tho I've ad 5 kids my 3 yr old is going though the check for autism but my 18 month old is worse then him never know a baby so quiet with cheeky grin dnt upstand basic thing his melt dwn are next level more so when he tired never no a baby scream 4 hole hr round a park coz they are tired and frustrated everyone going he's not happy or the fresh air knock him out yeah right
A toddler with a short attention span is not abnormal honestly. No toddler have long attention spans lol but as for everything else, have you talked to his doctor?
