Why does my baby's nighttime sleep get shorter as they grow?
⚡ Short answer: As a natural part of sleep development, as babies grow, their daytime naps decrease and nighttime sleep becomes more organized—but nighttime sleep duration usually doesn't shorten; instead, it typically lengthens and consolidates into blocks.

I've noticed my baby's nighttime sleep is getting shorter as they grow; is this a normal change?

As a natural part of sleep development, as babies grow, their daytime naps decrease and nighttime sleep becomes more organized—but nighttime sleep duration usually doesn't shorten; instead, it typically lengthens and consolidates into blocks. A newborn sleeps 16-18 hours scattered throughout day and night, while between 6-12 months, nighttime sleep settles into 10-12 hours, and after 12 months it's usually stable around 11-12 hours.
If you're noticing a marked shortening in your baby's nighttime sleep, it's usually due to a temporary factor like a developmental leap (sleep regression), teething, illness onset, or daytime sleep being too much or too little—these are common short-term phases that often resolve within weeks. If the shortening lasts more than 2 weeks, distresses your baby, and affects daytime functioning, consulting your pediatrician is worthwhile. By the way, how old is your baby? With that information I can give you more specific guidance.
