Hello everyone! I want to ask, what could be on my daughter's face? When she sleeps it disappears, when she wakes up it reappears (I added photos). The doctor says that maybe it's diastasis, but I haven't eaten anything sweet and I didn't drink anything sweet either, I haven't consumed anything that could cause an allergy, ? What could this be? Could anyone have encountered this, is it something that happens from birth ?
