Caleb has taken up to 4 steps unaided at 9+ months but hasn't progressed much, preferring to crawl about ATM but still doing the walking thing when he feels like playing.

Both his brothers didn't take any unaided steps till over 12 months and then they were off walking constantly.

It's almost like Caleb thinks that now he's taken steps he's not in a rush to go any further and will continue to do stuff in his own time

Who knows when you DD will decide to make walking her full time thing
