5. Hyperactivity
Children suffering from autism tend to be overly passive within the first year of their lives. However, as time progresses, they tend to become more active. Hyperactivity related behaviors you are likely to notice in children with attachment and development problems include constant crying and lack of physical tranquility.
6. Lack of Desire to Feed
Research found that a significant percentage of children with autism tend to have difficulties eating at different levels. These could range from difficulties in breastfeeding, transitioning to bottle feeding or even from liquid foods to solids. When they do eat, it’s usually in small quantities. These signs can be easily detected within the first few months after birth.
