Because I can\'t determine the reason for LO\'s dry cough at night, this prevents the house from running (except him! ) I am looking for ways to reduce allergens. I cleaned his room from top to bottom with a master cleaner from Honest Company and I have washed everything ( Baby crib, plush toys, pillows) In hot water and baby detergent I shut the cat out. ( I am also 40 years old and I secretly hope that cleaning up the skirting on my hands and knees will bring Labor! ! ! ) I want to buy an air purifier for his room because I don\'t think it will hurt anyone. Does anyone recommend it? There are so many choices! I saw a lot of \"good for small nursery\" but his room was not small. . . it\'s 15x15 (feet).
