Is anyone else’s pediatrician delusional?

Yesterday was my LO’s 6 month well visit. The Dr asked about sleep and I proudly said “She does 6-7 hours at night before she wakes up to eat!”

Then doc told me she should be sleeping through the night. She said it’s best for brain development for LO to have 10-12 hours of uninterrupted sleep at night. I mean, she’s sleep trained. She just wakes up to eat once around 2/3 and goes right back down (usually, we are getting over an illness so sleep has been dicey this last week). I feel like expecting her to sleep 10-12 hours is a big ask.
