My dd (14 months) has been at nursery since 4.5 months, and started on formula milk at about the same time. Ever since then, she seems to have one cold after another. Not sure it's cows milk related (been on goats milk formula for the last month with no difference), and everyone says that kids at nursery always have colds. This seems excessive though. Doctor and HV don't seem at all concerned. Is there anything I can do to help her or has anyone else experienced this/know when its likely to end? She's cheerful, alert, eats & sleeps well. Any thoughts appreciated
