Teigen has dealt with her fair share of mom-shaming comments lately. Last week, one commenter indirectly questioned why Luna was visiting the dentist for the first time at age 3. “So proud of my toons at her first dentist appointment!!” Teigen captioned her Tuesday post, which featured Luna sitting on her grandmother Vilailuck Teigen‘s lap as the little girl helped brush the teeth of a plush alligator. “What age do they start over there? My daughter started seeing a dentist at a yr old,” the user responded quickly.
