I had to go vet her birth certificate by public transport and ther is little boy keep coughing next to us and i am so.scarrf now she will get it. But to be honest my son startrd to cough aswell now so i guess he has cold already. Did any of you ladys had this? When your new born had cold before their first vacations? Xx
