Hope you are communicating well with your baby. Babies who sometimes cannot reach out to their parents may tend to show some qualities that will earn them your description (naughty). It's best you understand your child and set standards.
Understanding how well your child can communicate is also a key step in finding out what’s causing the aggressive/naughty behaviour. When children can’t express feelings or ask for what they need, they might use aggressive behaviour to communicate.
It can be helpful to ask yourself if the child is trying to tell you something. An example is, if your child doesn’t like a particular activity or food but can't tell you.
