Pediatrician’s food recommendations

We had our 6 month check up today! We’ve been introducing some solids the last couple weeks since by girl is 6.5 months and has seemed ready for a while!

I’m just curious when everyone else’s pediatrician said to add in meat, and water? Also allergens like peanut butter?

Ours said no meat until 9 months, and no water, juice or peanut butter until 1 year.
