Feedings during the day

Tori • Mommy to👶🏻❤ baby girl 03/30/2018, baby girl 12/31/2019

My little one is 18 days old and back at birth weight. Usually she eats every 2 hours, today she is going 3 hours during the day. She last ate 3 hours and 20 minutes ago and is fast asleep.

At night last night she did 4 hours and two 3 hour stretches.

Should I wake her up to feed her if it's been 3 hours during the day? I dont want to do all 2 hour stretches at night tonight.
