Which sleeping pills are safe while breastfeeding?

Not many. I don't think any of the prescription sleeping pills are safe. Otcs contain antihistamines that can decrease milk supply, so that's not ideal either. Perhaps the best "sleeping pill" would be warm milk, a relaxing massage, or snuggle time with your partner.
Not many. Benadryl (diphenhydramine) is resonably safe but may decrease your breast milk supply. Other sedative medications will make it difficult to respond to your child when they need to feed and may cross in the breast milk as well. Self hypnosis works well with no side effects.

Is it safe to take sleeping pills while breastfeeding?

Probably not. It depends on the particular med but most sleep aides are contraindicated while breastfeeding.
Many variables. It depends, which sleeping pill are you taking? How long are you taking it?, will you still wake up to attend to your babies needs? How old is the breastfeeding infant? It is not the ideal not so much because the drug will harm the infant so much, but can you be awake enough to care for the infant. It is probably best to avoid it, but if you have an absolute essential need for one time use maybe.
Probably wouldn't. It is possible that the medicines will be found in the breast milk, and so, to be absolutely safe, I would avoid taking sleeping pills while you are breastfeeding your baby.
