how many days cold will be there in newborn babies and when do we worry my baby is 25 days old. sometimes she breathes different and making noise

A. If you don’t treat then usually within 5 to 7 days it should get little better but there is no confirmation whether it is going to be completely sorted or not and says the child is so small they get irritated very fast so we always recommended to give medication it can take 5 to 7 days in some cases to subside completely
