14 week old suddenly feeding less - is this normal??

[ThisRubyTraybake]

My first post! I have a DD, born at 26 weeks - she's now 28 weeks old (but obviously not a normal sized 28 week old!). She is exclusively ff (I was expressing while she was in hospital, but my supply was never enough and tailed off entirely) and generally a good and regular feeder.
The past two weeks or so, she's been gradually increasing her feeds from 3.5oz to finishing off 4oz at a time, feeding about 8 times a day. But today has been weird - normal feed first thing, but I've been lucky to get 2oz into her per feed since, despite usual hunger cues. Seems otherwise fine, nappies normal, maybe sleeping a bit more.
No dp to reassure me, so looking for a bit of wisdom - does this sound normal?
Thank you x

So she’s about 7 months old now? Have you started weaning as that could impact milk intake. Sometimes like us, babies have days where they are hungrier than others.
Is she teething or does she have a temperature?Both can also affect feeds. Maybe just double check both.
Keep an eye on how much she’s drinking today and if she’s hardly having anything then maybe call the GP if you’re worried. If she doesn’t have a temperature, has wet nappies and doesn’t seem to be in pain or too irritable then I wouldn’t worry too much just yet.
