I was wndering if anyone can give me some advice before I go running to A&E as a panic stricken first time mum ! my 3 week old boy has started this morning a kind of rattle when he breathes, if he was an adult you would think he needs a good cough. Both me and my partner have had colds in the past week. My little boy is still breastfeeding and generally seems fine, is it just a cold ? im in a bit of a panic as its my husbands first day back at work :(
