"Oh he's almost there!"

"It's going to happen so soon!"

"He's almost got it!  I bet it happens this weekend!"

I try not to pay too much attention to milestones.  I certainly don't care if they happen early or late, and it doesn't bother me when another baby checks something off before we do.  I know it will all happen eventually.  If anything, I usually tell myself whatever it is will happen way later, so that I'm pleasantly surprised when it does happen.
