How long does this usually last?

So I've read that it's normal for LO's to wake up in the middle of the night when they've reached a milestone and what not. Dd1 never did this, but dd2 has. Now that she's started walking, she gets up and stands in her crib and I'll have to lay her back down and she goes back to sleep. It's been about a week or two now. How long until she just stays asleep? Lol. Is it not going to be until she's probably perfected her walking and is running around so much she'd be too tired to get up at night?

idk, my 2.5yrs sleeps through the night,but about 1-2 times a week she ends up in bed with me.
Babies/toddlers start sleeping through the night at all different ages.
