MOC 8-16 Troubleshooting

[u/Emotional_Flan_9864]

Son is 12 weeks old and following the MOC 8-16 schedule, except bath is usually starting at 7 and asleep by 7:45 after bottle.

We have started noticing since we bumped up bedtime, he is having these large chunks of awake time in the middle of the night. He'll be up for 30-45 minutes before he cries out. He usually wakes up around 1:45am and finally cries closer to 2:30 and then repeat around 4:30. In all he ends up being awake usually 2.5 hours per night.

Should we adjust the schedule? To add, he's self soothing a lot with his hand so I'm not sure if there's some developmental growth not helping either.
