So hungry some days... Growth spurt?

Alicia
Probably a silly questions... But there are days I am so hungry and I am eating what I normally eat: bowl of cereal and fruit in the morning...salad, chicken, fruit and granola bar for lunch.. And salad, vegetable, and a protein of some sort for dinner.. With an occasional indulgence of a dessert at night. Anyway, I am 25+5 days and I have been starving the past few days. I obviously satisfy my hunger pangs, but curious... Growth spurt of the baby?
