Sleeping all day after cluster feeding?

Jennifer

My 3.5 week old is coming out of at cluster feeding phase (πŸ™ŒπŸ»πŸ™ŒπŸ»πŸ™ŒπŸ»πŸ™ŒπŸ»πŸ™ŒπŸ») but has been sleeping allllll day for the past two days. Before she was cluster feeding, she had a good schedule of being awake for a few hours in the morning and a few hours in the afternoon/evening. Now she pretty much wakes up to eat and right back to sleep. Is this normal? I thinking it’s due to a growth spurt she was cluster feeding for.
