The baby center website growth chart says average weight
for a 33 week baby
is 4.23 pounds, and that your baby
is the size of a 32 week baby
, which is 3.75 pounds. Your baby is REALLY close to average.
Of more concern is your other post that states they've found a placental leak - indicating your baby isn't getting all that your placenta is delivering. The good news is, this has been discovered and is being monitored.
