Potty training regression is real and I'm tired

So our 3yo was doing great. Like genuinely great. Been using the potty for solid 2 months. New baby sister arrived 4 weeks ago and suddenly we're back to accidents daily. I KNOW this is normal and developmentally expected but good god it's exhausting. Just needed to vent. Anyone got actual strategies beyond "be patient" because I'm already doing that and I'm running out of small pull-ups.
