How often are you feeding your older babes?

My almost 10 month old has 3 meals a day + a snack. She doesn't eat a lot of it, but her stools are turning thicker so I know she's getting some down. I feel like she's taking in less milk. I nurse on demand because we can. We nurse to sleep and usually nurse over throughout the night, but not for very long. I feel it's more for comfort. We also do thawed breast milk in an open cup or straw at meal times.

How often are you nursing your older babes? I feel like I should be nursing more, but I think she's content??
