This is my 9mo. Takes me 45 minutes of a morning to dress her. That isnt including changing her nappy. And we use cloth nappies with snaps. So harder to do while she is rolling around acting like a fruitloop.
I make a game of it and also hand her whatever is in reach that will stop her rolling and crawling around the change table. She hates lying down so I sit or stand her up when her nappy is done to dress her. Distraction is definitely the key.
As for discipline as Vp said I dont think there is such a thing for a baby. While he is getting a reaction its a fun game. Redirect his attention when he bites to something else and just a firm no. He will pick it up.
