Good evening, I have a daughter who just had her first baby 6 months ago. The baby is using a pacifier. My daughter and her husband have 5 dogs and 3 cats so there floors are dusty. In addition they live in Tucson, Az. Every time the baby drops the pacifier from her mouth, they insist that it is fine to put it right back into the baby s mouth w/o washing it off. My granddaughter seems to have a constant cold and I am concerned that it is related to always placing a pacifier that is not as clean as it should be in her mouth. They claim their Dr. said it was alright to place It in the baby s mouth after being on the floor as this will build up immunities. I worked 23 years in a state health department and we never utilized that idea with with our new mothers in parenting classes. I not sure they have discussed with their Dr. that the house has 8 animals in it. What do you suggest I do in this situation. I m thinking of accompanying my daughter and the baby to her next Pediatric appointment and inquiring about this situation. They may have not shared with the Doctor the number of animals in the house which causes a great deal of dust and dirt. Am I correct that it is very unsanitary to keep reintroducing a soiled pacifier back in the baby s mouth and this could lead to health problems for the baby. Thank you in advanced for your thoughts.
