How to make my baby feel better if she has a cold?

I use this when my lo has cold or cough. Rub abit on her chest, back and soles of the feet. If shes still young, might not be suitable to rub on nostrils. Use a humidifer in the room if she is sleeping in air con room. Air con usually dries up the air so that will help. Good to drop a bit of eucalyptus in the water. Just a little. Hope she gets well soon!
