It is not true that a wild mother will not take her babies back after they are touched by humans. You may need help if the animal is large. Use nets, gloves and blankets to capture. Do not put yourself in danger. Make sure the animal is an orphan.
Animal mothers leave their babies for hours at a time in search of food.
Unless the babies are cold or injured, leave them alone and keep an eye on them for several hours before you decide to rescue them. Do everything in your power to keep the baby with it's mother. Keep dogs, cats, and children away. You probably won't see her. Put the bunnies back in the nest.
