Strangers comments about my baby

I am soooooooo tired of people commenting about how “small” my 1 year old is. Just yesterday at breakfast a woman said her 4 month old grandson is bigger than him. GREAT. She was shocked to learn he was 12 months. I KNOW he’s small. We were hospitalized 3 times within his first year of life because he had feeding difficulties. He had a nasogastric feeding tube for 6 months of his life. He did feeding therapy for months. I KNOW he’s small and it gives me debilitating anxiety almost everyday. I don’t need random strangers to remind me. It makes me not want to take him anywhere because I almost feel embarrassed, and I SHOULDN’T feel that way. Can we normalize not commenting on baby’s sizes… big or small!?!?!?!? We have a genetics appointment next week because I’m so worried about his weight. It was my own personal recommendation, his pediatrician said he’s fine but the comment after comment has made me believe maybe we’re missing something!?!! Ugh. That’s all. If you’ve made it this far, thanks for listening.
