1% at 36 Weeks - Experience ?

Hi - not technically a NICU Parent yet - but seems inevitable. Growth scan at 36W showed baby was 1st percentile (possibly a bit under). They had been keeping an eye but don’t seem to have paid enough attention until this most recent doc. Estimate is around 4lb5oz. They plan to deliver at 37W. Wondering if anyone has similar experience and what the outcome at birth was ? Were you able to have a vaginal birth or c-section (this is my second. First was vaginal birth to a small baby but over a pound more). What did your NICU stay look like - worried and confused ! He’ll be “term” but measuring much behind…. They gave me this info all at once during a very brief appointment, so any information/success stories appreciated !
