A humidifier falls into our list of nursery nice-to-haves, rather than nursery must-haves. It’s not necessary to have one on hand, but it might be helpful in certain circumstances. If your baby was born during the colder months and your heating system makes your home particularly dry, a humidifier could be a great addition to your nursery. It’ll keep congestion and dry skin at bay. Cool mist humidifiers are a great option, since they eliminate the burn risk for you and your baby.
