How do you know your child is developing autism?

Pay attention to delays in developmental milestones. Lack of eye contact is one main sign. Other signs are; lack of social interaction and responsiveness to social cues e.g. you imitating a simple action and the baby cannot attend to it or imitate it. Lack of joint attention — you pointing to something and baby cannot look in that direction. Another m is atypical behavior e.g. excessive crying, screaming etc. tantrum behavior, getting upset very easily. Every little thing may easily trigger these behaviors in the baby. Heightened sensitivity to sensory stimuli, such as with sound, smell, light, textures, tastes, certain environments, etc. all these signs vary, this is why it is known as autism spectrum disorders. The spectrum of autism range from mild to severe.
