I have a question as I am a first time mom here...how long after ur baby drops was it til u went into labor? my lil girl is head down and ready to come already and I started to drop the other morning at work and she has stayed down...I only really feel her move down low and not as much as I did before...and I know that's a sign of them getting ready to come so I was just wondering if u could lmk how long after ur baby's dropped did u have them...she needs to stay in there for at least another 4 weeks if not longer to b almost full term...
