S.B.
She's learned how to stand up and that's a prelude to walking.
It's a new skill. Bound to happen sooner or later.
It's my opinion that she's not hungry. She's just waking and she knows how to pull herself up. It won't hurt her to let her cry a bit. At 10 months old, if she isn't hungry, she can learn that being awake doesn't have to mean the rest of the world is up and rocking.
One good thing about little children is they don't have far to go to get back down. She will learn to use her tushy for that purpose.
Once they learn to grab the rails of the crib to stand, they also learn how to use them to slide back down.
If it's taking an hour or two for her to go back to sleep with you getting her up and nursing her, what could it hurt for you to let her have say, 20 minutes to roll back down on her rump and try to go to sleep?
10 or even 20 minutes can feel like an eternity, but it really isn't and she'll never know how to sleep on her own if you don't let her try.
Keep in mind that babies change sleep patterns with new skills and it's okay. I personally just wouldn't rush in and I would let her have a bit of time.
Some kids wake up, stand up, jabber, roll around....it doesn't mean they need to be picked up. It doesn't mean they need to be "put" back down.
A 10 month old waking every two hours just needs to be given a chance to drift back off. She's not a newborn. She's in exploration mode now that she can stand in her crib.
Just have some patience and really try to let her go back to sleep. Just being awake is one thing. If you know she's not sick or hungry, she needs to figure out that the world isn't up 24/7.
You'll make it through this.
Best wishes.
