Dehumidifier helps with breathing and air purification system for air born allergies. The Chlor is an antihistamine same as benedryl - there are 4 different kinds and some dogs do not get relief from them hopefully your baby does. It is safe as dermatologist had us do a trial - and she stated allergies start from 6 mos to 3 years and my dd started at 6 mos
hers is severe itching though and more skin issues - very frustrating
