My LO is coming up on 9 months and isn't showing any signs of crawling. The questionnaire for this upcoming ped appt asks about crawling, pulling up, and cruising - none of this behavior is happening. My daughter rolls like crazy and will stand if I put her in that position. She does not get her torso off the ground, and resists my attempts to show her by planking, pretty much (girl must have abs of steel). We have lots of playtime on the floor everyday.

How old was your LO when they started crawling? Did they show signs of figuring out our before they started, or was it all of the sudden? Is my LO late or am I worrying over nothing?

Thanks in advance
