My formerly good sleeper has started waking up at around 3:30 about half the time. He used to sleep reliably from 8pm-5am, and when he would occasionally wake up he would usually soothe himself back to sleep a vast majority of the time.

He's only 7.5mo, but this all started a few weeks ago when he learned how to crawl and pull himself up to stand. I think he is just more alert and ready to play when he wakes up in the MOTN.

Last night I checked on him and then waited almost an hour before I brought him into bed and nursed/slept til our alarm went off. This is not sustainable! The bedrooms in our apartment are adjacent, so I can't sleep when he is screaming.

A few times when I brought him into bed, he nursed for a bit then woke up and started crawling around and trying to play. So, I would just chuck him into his crib.
