Q&A: Length Of Growth Spurts?
Help! My baby is going through a growth spurt. How long will this last?
Growth spurts usually last for about 24 to 48 hours and boost your milk supply to meet his growing needs. (Some moms say they can stretch to a full week.) During this time, baby will want to nurse frequently (sometimes as often as once every hour) and might be a bit fussier than usual, which is totally normal.
