15 m DD not eating much last few days

[winnybella]

I know toddlers can be fussy eaters, but DD always ate well, decent portions for every meal and bf 2-3 times a day.
Last few days, though, she's been barely touching her breakfast, eating maybe a third of her lunch, half of her dinner. Bananas she was always crazy about are chewed for a few seconds before being thrown on the floor.
Is it normal? I mean being a good eater and then suddenly becoming a fussy one?
She doesn't look like she's coming down with anything, teething- perhaps, but it doesn't prevent her from sleeping well so it can't be that horrendous.
Few days ago I lazily gave her some pasta with a tomato/ricotta sauce out of a jar and I realised after she ate some that the sauce went bad/sour (unopened and good brand, v.weird). But nappy's are fine so surely it couldn't have been food poisoning that's affecting her eating now?
Am a bit worried about this sudden change.

For breakfast today, since the usual porridge/milk/whole banana was met with disapproval these last few days, today I gave her just 2 rice cakes with butter and a bit of jam and half a banana. She licked the jam off, had one tiny bite of the rice cake and of banana and that was it.

Anyone else had similar experience?

Doesn't sound unusual tbh. DS (now 22 months) has gone through stages of going off his food. He has also gone off things that he's previously loved. I figure he's maybe got bored of them or just developing his own tastes. I wouldn't worry too much.

My DS has done the same thing from time to time and then had a massive eating spurt to make up. With hindsight it has usually coincided with teething or coming down with a cold etc

Ok, thanks. She actually ate a reasonable amount of food for lunch, so maybe she's just going through a phase/teething/likes being contrary.
