Growth Spurt

We have such good baby. From the day we brought her home from the hospital she's been so good!! She's pretty much been sleeping through the night and not very fussy at all from the beginning. Lately though, she seems to be fussing a lot more...especially right around feeding time. She'll act like she wants to eat, but won't. The doctor had told us that she may be going through a growth spurt around this time...so we're thinking that may be part of it. Can't really think of what else it could be.
