My 4.5 yr old child s speech is little difficult to understand by others, when i consulted speech therapist (by sending vedio of my girl talking), she suggested to get a psychological assessment done to see wether my child thought process is right.Why did she suggest that? My daugther mingles with all and likes making friends, maintains eye contact does school works (not always but mostly) Our concerns are that she recently developed habit of nail biting which turned to nail picking (all the time) , she still uses breast as pacifier to sleep ( without that she cant fall asleep), she is toilet trained and can dress herself put socks and all but cries when asked to eat herself (so lunchbox is returned without eating from school).When she was a child also we had very hard time feeding her, she refused to take breast milk and bottle milk so had to feed her little by little in her sleep. She also still has gastric issues occasionally (doctor prescribed lansol a number of times)
