Hi all, just looking for a bit of advice. My 7 week old has started vomiting on and off this last week - one a day, although not in the last two days. Today she vomited straight after her morning feed, with it finishing with bright yellow liquid. A call to 111 told us to wait until tomorrow and then get a doctor's appointment. Each time she's thrown up she's seemed fine, and today she was smiling straight after, so doesn't seem to be uncomfortable. Any ideas what could be up with her?
