Is it natural?

I did the calculations and from 8/12-8/30 I pumped an average of 1070ml. But from 8/30 to now I've been pumping 930ml.

Nothing's changed about how often or long I pump. My baby started solids about a month ago now - she still takes the same amount in her bottle every time but I would usually be able to store away an extra bottle.

I'm not sure if maybe it's just natural. She is almost 8 months in October... She sleep through the night for the most part, falls asleep around 9-11pm and wakes up at 5/6am by then she needs another bottle and diappy change then she's back to sleep til 9/10am.

I did drop a pump session back on July 25th but my expression stayed the same amount until August 30..
