My baby is 1 year and 3 months old. From yesterday she is breathing through mouth, but she has a cold and running nose as well. Is it normal during cold or does it means she has swallowed something because for past two days she was not eating much. she is not completely breathing through mouth but sometimes she is having difficulty breathing with nose and other times she was fine. please suggest is this normal or do I need to have a check with pediatrician.
