Any tips on how to help a baby (6 month old) sleep while congested. We have a cool mist humidifier running, we use saline & suction his nose when needed. We even tried elevating his mattress a little (a slight incline). Anything else we can try? Naps are almost non existent as he wakes up within minutes of being laid down. We are brutally tired after 3 nights of him waking every 20-45 minutes. Bed sharing is not an option for us & holding him all night is not sustainable with a toddler.
