Picky eating can sometimes be a sign of autism but just being a picky eater doesn't mean the child has autism.
A lot of young children are picky eaters and it can be a challenge to get some young children and toddlers to eat what is put in front of them.
My kids were all picky eaters and they are not autistic and I was a picky eater myself as a child.
Some behavioral signs of autism include inappropriate social interaction, poor eye contact, compulsive behavior, impulsivity, repetitive movements, self-harm, or persistent repetition of words or actions.
Developmental signs of autism are learning disability or speech delay in a child.
Cognitive signs of autism are intense interest in a limited number of things or problem paying attention.
Other signs of autism are unaware of others' emotions or depression as well as anxiety, change in voice, sensitivity to sound, or tic.
Some kids may have a less severe form of autism and may be normal in other ways but if they have poor eye contact then it can mean the child is either just shy or has autism.
