eveieHi there,
My 11 month old has sort of chubby cheeks as compared to her weight. She is just the right weight for her age and is actually kind of on the slim side. Anyway, I'm also thinking 'baby fat' as most of babies tend to be cheeky but I heard my endo. mention in passing that her cheeks are due to the meds but soon go away as she gets older.
I read that oversupression can be a cause for so called, moon-face, but she is NOT oversupressed. So, as for my little girl, I am not so sure it's the meds. or just a normal thing. She looks so cute with her little cheeks anyway so it didn't bother me too much but the same ques. as Angela have crossed my mind.
