Anyone’s baby still not “pulling up to stand”?

lo

Baby girl turned 9 months on the 11th. She is still not crawling or pulling up to stand. Besides that she is the healthiest little baby!

The doctor told us today that if she isn’t pulling up to stand within a month, that we need to have early intervention or something to help her.

So now I’m worried. Anyone else’s little babies not pulling themselves up to stand yet?
