Why does my older sister, aged 13, not want to play LEGO with me anymore and stays in her room the whole day? – Beth, age 10, Australia.

The full article featuring Prof Jayashri Kulkarni is in "The Conversation" 

I am sorry to hear your 13-year-old sister does not want to play LEGO with you anymore and stays in her room all day. This must make you feel sad and maybe a bit rejected.

It is not your fault. There are many reasons why this could be happening and I can’t say for sure what it is. In this article, I am going to talk mostly about one of the possible reasons that could be involved (but it may not explain everything).

Like many 13-year-old girls, your sister is going through a change in her mind and body called puberty. It may be making her behave differently. Puberty is when your body changes from being a child to becoming an adult.
