Christy, not sure how old Gemma is but you can use baby vicks from 3 months. If Mackenzie had a blocked nose I would rub some on her chest as the vapours would help her with her nose. I'd also roll up a towel to elevate her matress which sometimes helped. She seemed to have a cold every day of the year from day one to 12 months so this is just the beginning! Good luck!
