No, apparently he prefers drinking out of cups.
Big-people cups, made of glass or ceramic.
The other day I gave him a bottle of breastmilk after he ate his sweet potatoes. He drank from it for a bit, but couldn’t get the “tilt” right and got frustrated. Then I poured it into a small mug, and he grabbed it perfectly and chugged it all back. He even sighed a little, like, Finally! This is more like it.
