Mine would eat off the kids menu at 8months. We didn’t go out that much once every couple of weeks so I didn’t stress about if the ingredients where a bit salty etc just for that meal
At 8m they ate food off our plate. But since maybe 12m we usually order him an adult meal. We find most kids menus are the same processed stuff.
When they are that little I would just take something for them or feed them before they go and give them a little something from your plate ☺️ seems a waste to order them a meal when they are so little and unlikely to eat it all!
