3 month old sleep issues?

Alyssa • Boy Mom ☺️💙🐶 Dog Mom

Hi Nov. Mommy’s! So my LO has been an amazing sleeper. For about the first 2 1/2 months of his life he’s been sleeping through the night. Most recently from 10pm-715 am (I know a dream). All of a sudden for the past 5 nights he’s been waking up earlier and earlier for a bottle. Tonight was 4am. He hasn’t done that since he was a newborn. He’ll be 3 months tomorrow. Could this be a sleep regression or something else???
