A few weeks back, Elsie got her very first cold. She had a very stuffy nose for a few weeks and then got a cough. We are lucky she didn't get sick at all until she was almost 7 months old! So for my future reference and anyone else who's battling baby's first cold, this is what worked for us.
Boogie Wipes Natural Saline Kids and Baby Nose Wipes for Cold and Flu, Unscented, 30 Count (Pack of 3) : for those crusty boogers, and to keep baby's nose from getting sore from all the wiping
Little Remedies Noses Saline Spray/Drops, 0.5 Ounce : to keep thing moist (yuck)
Nasal aspirator: we have the good old fashioned kind, and I'm probably the last mom on the planet to have not used the Nose Frida, but we have managed to suck out many a boogie with the basic aspirator
Crane Usa EE-3186 Elephant Cool Mist Humidifier : works wonders on stuffy noses! I put it on at night and during nap times. I actually plan to use it in Elsie's room all winter because we have radiators here which dry up the air
Also, for really stuffy nights, I have elevated one end of Elsie's crib mattress which seems to help a bit.
It's really tough when baby catches a cold because they just don't understand why they feel so gross but it will pass.
