Yes! Sleep regression around 4 months is super common — it's when a baby's sleep cycle starts to mature, and they wake up more often between cycles. A few tips that help:

Stick to a consistent bedtime routine (bath, feed, lullaby, etc.).

Watch for wake windows — babies that age often stay awake 1.5–2 hours max before needing sleep.

Encourage naps during the day — overtired babies sleep worse at night.

Try to put baby down drowsy but awake to help them learn to self-soothe.

White noise and a dark room can also work wonders.

It’s a phase and it will pass — you’re doing great! 💪🍼

Seconded on most of this. Especially dedicated bedtime routine and preventing overtired baby with decent nap times.

Another trick that my wife was super against until our midwife talked about doing it and we had a horrible night and she was just exhausted, but side lay breast feeding. My wife on her side and the baby able to breastfeed and then just fall right to sleep. Saved us numerous painful nights that turned into short little wake periods and back to sleep.

Until we did that a bit I was just getting up and walking with them in the night. We are going through this same regression right now with our daughter. I mostly just end up walking with her at least once in the night and my wife’s will feed her once or twice. She’s 5 months now and it’s improving
