Baby eczema not going away?

Our little dude has had eczema flare-ups since the winter started. We have visited the pediatrician multiple times and have received different creams and ointments. The eczema hasn't responded and now the poor guy is getting red scaly dry patches in his crevices (armpits, thighs, chest - he's a chubby boy)

We have an appointment with a dermatologist Monday - but has anyone else had to deal with us? Luckily the pediatrician says she doesn't believe it is anything serious because he doesn't have a cold/fever/low energy, nothing like that.
