5 year old Is it normal

Is it normal for a 5 year old boy to be taking off his 1 year old sisters clothes? He knows it is wrong and sneaks into her room.  So I was wondering if it normal and what can I do about this situation please I need your help.

To answer your question,it really depends on if they are playing games like dress up or house or if he's just doing it just because. Have you ever asked him why he does it? What does he answer back? If you feel uncomfortable about the whole situation, then you need to set some strict rules to this for him to follow. He is old enough to start to know right from wrong. Keep a very close eye on it. Maybe he does it for attention. My daughter used to dress her brother in her dresses all the time! I thought it was funny but their dad thought it was completely wrong and didn't see how they were playing dress up together! It was just a innocent game she was playing with her brother. That was 5 years ago. til this day, they still play house and all sorts of other games amongst barbies boardgames, outside games,etc.If you uncomfortable with the situation, then tell him and be persistent about it. I hope this helps.
