Not a growth spurt
Babies go through growth spurts, in which they seem to eat all the time, and then slower periods of growth during which they do not seem to be as hungry.
You might worry if your baby isn't feeding
because she doesn't seem to feel good, is lethargic, or has fever
or trouble breathing. If she looks and acts healthy, it may be a temporary slowdown in her growth. She may be eating more per feed, too.
