If your child has allergies, here are some tips from New York-Presbyterian Hospital to make those allergies more bearable this winter:
Keep your home's indoor humidity level below 35 percent to help prevent the growth of mold and dust mites.
Don't put rugs or carpeting in your child's room.
If you have a humidifier in your house, clean it daily and change the water frequently to avoid contamination by mold and bacteria.
Don't keep plants in your child's room, because decaying leaves and increased humidity can boost the growth of mold.
Keep vents and filters clean, to prevent accumulated dust from being blown into the child’s room.
