In breaking Dawn does edward bite bella or does his venom in the needles turn her???

Actually both. Initially, he injects his venom with the needle which is the main fonte in her body then he also bites Bella on her main pressure points.

first off he injects her coração with his venom in a needle, then he bites her in as many places as possible. He also goes over all her major cuts that had occurred while he was delivering the baby with his tongue, sealing them shut.

well both really

no when bella is haveing Nessie edward bites her because she is in pain
