I'm so bugged... yes my almost 3month is sick..but she isn't as sick as she was her cough is so much better and she isn't coughing all day..just a couple times...I do realize that she could be sicker then I think.. but her big brother has been sick since the 9th she got sick the 11th...brother is all better...she is getting better...you don't always need a doctor when you get sick...it's a cold..I'm just so tired of my inlaws telling me she needs a doctor...I don't like hearing my babies sick or hurt anymore then you do..but i have talked to her doctor she can't take cough medicine she is to little...the humidifier makes her worst...just like it does for me..I did find some mucus reducer medicine for 2month olds a zarbees brand..it seems to help and I've given her little of infant Tylenol...but idk...maybe everyone is right maybe she has more then a cold...but I dont see the point of paying for them to tell me keep doing what I'm doing..or yes she is super sick..but she can't have medicine anyways so she will have to tough it out..I think I would know if my baby was super sick tho or had something wrong..and I'm not the one to avoid doctors and what not...when my kids get hurt or get sick...I'm all over it...stress for no reason..just cause I want the best for them
