DD2 is cutting some teeth right now and even ibuprofen is providing no relief. Her nose is a faucet and her drool is coming out in buckets and she's coughing I'm assuming due to all the extra saliva. I gave ibuprofen right before bed and she was still up in 45minutes then again 2 hours later crying. It took me almost two hours to get her back to sleep!
I've got a cool mist humidifier with eucalyptus oil to help with the coughing in case it's not due to teething.

What else can I do to help her sleep and ease her discomfort?

My older daughter was such an easy teether!
