my baby is 9 weeks old and she's been coughing, sounding hoarse and v.sleepy, wakes up crying looking for my boob, eats little and goes back to sleep...I have also been coughing with a sore throat, so assuming is the same. no temperature. hv suggested cooled boiled water but she's not taking bottle (she normally does) any suggestions on what can I do to make her feel better?
