MIL dropped off M after babysitting and asked, "don't you think she needs more nutrients?"
I replied, "Erm, well, I'm also giving her some fruits and vegetables."
MIL clarified, "I don't think she's getting enough nutrients from just drinking milk. Don't you think she needs fibers and proteins and minerals?"

😱😮😐😐😐😐 😶 (exactly what my face must've been like)

Then she hands me one of those food pouches... For stage 4. M is not even crawling yet and no teeth...
