Hello fellow mums, I wonder if any of you have been there: my 9 month old DD rubs on her nose very often which is usually followed by crying or irritability. I tried to do some research and the only thing that comes to my mind is (i) teething, or (ii) according to some, could be parasites (we've been on holidays recently and most certainly a few sand grains landed in her mouth whilst on the beach...). I wonder if any of you had similar experience and figured out the cause (before I head to a paediatrician)...
