Breastfeeding

So I finally got my boy home from hospital yay, I'm trying to breastfeed he can latch on perfectly and feeds well until he is satisfied then sleeps for 3-4 hours. The problem that I'm having is that I'm creating enough milk to feed the entire population, literally he is soaked I'm shocked all down my trousers bras tops arms everywhere! And they are starting to get a bit too full an painful

Has anyone know how long this lasts will it settle down soon? And is it normal xxx
