Signs It's Time to Stretch the Wake Window
Your baby won't stay on the same wake windows forever. Here's how to tell they're ready for a bit more awake time:
- It takes 15+ minutes to get them to sleep for every nap
- Naps get shorter without anything else changing
- Your baby is all smiles and not remotely sleepy at the usual time
- Bedtime shifts later or they start waking more at night
If you spot a couple of these for several days in a row, try adding 10-15 minutes to the wake window and see how it goes.
Common Sleep Problems at 4 Months
If sleep has gone a bit sideways, you're not alone. Here's what often trips up parents at this age:
- The 4 month sleep regression often causes lighter sleep and more night waking.
- Rolling can disrupt sleep until baby gets more comfortable.
- Waking every 1-2 hours is common during this phase.
- If the fourth nap becomes a battle, it may be time to move toward 3 naps.
What to Do During Wake Windows at 4 Months
Not sure how to fill those wake windows? Here are some age-appropriate ideas:
- Tummy time with toys just out of reach to tempt them forward
- Propping them up in a supported sitting position to see the world
- Grabbing, mouthing, and shaking toys (everything goes in the mouth now)
- Floor time with a baby-safe mirror
- Splashy play on a water mat
- Music and singing
