14 Week Old Randomly Not Eating Today

My 14 week old randomly seemed not hungry/interested in eating. First time she’s ever been like this!

She’s been going through a big developmental leap and having nap and sleep regressions and longer wake windows, but this entire way she’s been crushing back 5 ounce bottles pretty consistently. Today she had her usual 3 ounce bottle at 3 AM and literally didn’t have more than 1 oz at her 7AM, 10AM, and 1PM feeds. She didn’t eat anything at her 4PM bottle. She’ll latch and suck a few times and then spit it out. She’s had a total of about 8 oz across 24 hrs today when her normal intake ranges between 18-23 oz in 24 hours.

She’s been smiley, happy, and playful like her usual self. Had a poo today and consistent wet diapers.

Has anyone experienced this? We plan to take her to urgent care tomorrow (it’s the weekend so Peds is not open) if she continues like this.
