If at any time, as a parent, you are concerned about your child’s developmental milestones: ASK your community nurse, GP, or specialist can provide guidance.
Anecdotal evidence (i.e.: other people's experiences) are not set in stone. What worked or happened with one person may not be the normal for you or the solution you need. It is information. It can help you work out what you need to know. But you need more than one person’s experience.
The variation of normal is wide. So wide, that a better question to ask is “is my child happy?”
Your child may not fit the stereotypes, based on cultural and media influences. We are all individuals, with different interests and personalities. And that is Awesome!
