I found this forum about scabies. There may be a bigger concern about them than you handling your baby, and that is the fact that they can spread onto furniture, and bedding and onto your clothing.
Be sure to wash your clothes separately from anyone elses clothing and wash in hot water or at least wash in vinegar. Till you are completely cured, I would avoid handling the baby or any of the childs belongings. It is better to be safe than sorry. I hope you have something that prevents your mattress from being infected. I know when my husband was in the military, there was a scabies infestation in the barracks. They all had to wipe down the whole room with watered down bleach and put their mattresses out in the sun and if they had somethings they could not bleach, then they had to bag it for 30 days. These mites still need oxygen and nutrients. It seems they do not do well in full sunlight.
When my husband came home from deployment a week later, I boiled everything he had and he had to sleep on the couch (which I covered with plastic) for a week longer till there was no proof he was free from scabies.
