During a growth spurt, baby may want to nurse more often and might seem hungry all the time. He might be fussier too. Take a mom who's nervous about her milk supply, give her a constantly fussy, visibly hungry baby, and panic is likely to set in. Luckily, you are an informed mom now, and you know that if baby's nursing more often for a few days, it's no big deal. If it's a growth spurt, in a couple of days, baby's feeding habits should be back to normal.
