12 week old sleeping 12 hours

So my 12 week old had to start daycare around 10 weeks. She doesn’t nap well there and sleeps a ton at night. I send her 9 ounces for the 8/9 hours I’m away and we nurse once before and once after daycare. She rarely wakes up to feed in the MOTN anymore. Not sure if I should be concerned, wake her to feed, or keep getting the sleep.

I’m worried both about my supply dipping and her weight. She doesn’t have another check up for a month. Pedi suggested maybe sending more in her bottles but obviously I had to Ask Reddit for the real answer.
