Looking for any suggestions-

Our good sleeper - bedtime at 7:30pm wake around 3:30-4:30am for a bottle and back asleep till 6am has started waking up at 5am for the day. Looking for any suggestions as to how to get that hour back.

He is 4.5months old (a few days shy of 20weeks).

His room is pretty much blackout.

No one else is up and moving around yet for him to hear.

He’s pretty good at self soothing for the little wake-ups in the night but needs help going to bed initially in the evening and feeds to sleep at the 3:30/4:30am wake up.

Any suggestions?

Thank you!!!!
