A 5" penis is perfectly normal.
i personally would be happy that my child of 2years is healthy ... but to answer you question science has not determined what size a 2 year old penis is ... and rightfully so ...
There is no "normal". The size you are is normal for you.
Everyone grows at their own rate so yes its normal
Any size is normal. Everyone's different.
Perfect length you have!
well it will be realy big but it will get bigger as they get older
