Does anyone else with older bubs find they have days where they're just not as interested in feeding?

Usually DS will feed quite frequently throughout the day, in addition to his solid meals which are a bit hit and miss about how much gets eaten. But every so often he'll have a day or so where he's just really not that interested, and can go several hours without a bf. Even if offered - he plays around, wriggles to get down and generally puts up a fuss rather than latching on. I'm finding it happens more often when he's just starting on a new skill, but sometimes I wonder whether I should maybe offer a bit more frequently even if he's not showing much interest?
