Why am I not getting notifications on my iPhon 5s?

Yesterday, I upgraded my phone from an iphone 4s to an iphone 5s. It seemed to take forever to transfer everything over and to set up the new handset. Everything is now set up and I have loggd into everything through the apps (facebook, twitter, instagram etc) however, I'm not receiving notifications on the 5s but am still getting them through on the 4s. What do I do to rectify this?
