Advanced LO means that a new one will be here soon?

Okay lol so I found this so funny so my daughter is really smart and learns quick. Well I posted a video of her doing tummy time on snapchat and she was moving her legs and not lifting her head ( so she basically gets the concept) and I kid you not 5 people snapped me saying " Oh she's already trying to crawl you know that means she's crawling out the way for the next one to come."
