It's not necessarily weird that you don't remember much from your childhood before the age of 11. Memory recall can vary significantly from person to person, and many people have limited or fragmented memories of their early years.
Childhood memories are often influenced by various factors, including the significance of the events, the emotions associated with those events, and how frequently they were recalled or discussed later in life. Additionally, memory consolidation and retrieval processes are still developing in children, which can contribute to the gaps in memory during adulthood.
It's common for people to have clearer memories from their adolescence and onwards because they have a more developed capacity for encoding and retaining memories as they grow older.
If you're concerned about your ability to recall childhood memories or if you feel like there might be underlying reasons for the gaps in your memory, it may be helpful to speak with a mental health professional. They can provide guidance and help you explore any potential factors that could be affecting your memory recall. But in general, having limited memories of early childhood is not unusual and is experienced by many individuals.
