Pulling to stand and 8 month sleep regression

Jacquelyn • Wife 💍 👭 - Fur mom 😺😸😻 - 6 IUIs - 1 👼🏽 - moved to IVF August of 2019 💉 - expecting our 🌈👶🏽 May 18 2020 - Benjamin 5/16/20 👶🏽💙

My son who was sleeping through the night anywhere from 11-12 hours straight has now started waking 1-2 times a night by pulling to stand in the crib.

The cribs in the lowest level for safety.

But he ends up getting sooooo worked up, he can't get back down and it takes 45 to an hour to get him back to sleep.

Anyone else going through this?!
