baby sister ultrasound

had an ultrasound today to help guesstimate how big baby sister is. the tech estimates she weighs 5 lbs, 2 oz, at 33 weeks & 3 days. at week 35 babies generally begin gaining a half a pound a week. i'll have another ultrasound in a few weeks to compare to today's, to try to see how fast she's growing, to make a decision about birthing options (vbac vs c-section).
