Is this sleep regression?

Mayra • Married to the love of my life 💍, mom to a beautiful girl 👨‍👩‍👧

My baby was sleeping about 4 - 5 hours at night. Then suddenly she is waking up every hour or hour and a half and wants to eat. She drinks about 3 oz of milk then goes back to sleep the. Wake up and maybe aeats another oz then wakes up and eats again.

From 9:30 - 6 am she eats about 6-8 oz waking up every hour is so.

Is this sleep regression? And how long does this last?

Baby is 14 weeks 😫
