Your 2-Month-Old: Development, Sleep and Feeding
By the Growbaby team · Published Aug 3, 2026
Written against AAP, CDC and WHO guidance. How we write these guides
At a glance
- The social smile arrives for many babies around 6 to 8 weeks.
- Sleep is still roughly 14 to 17 hours a day, with slightly longer night stretches emerging.
- Wake windows stretch to roughly 60 to 90 minutes for many babies.
- Crying often peaks around this age, then gradually eases.
- The 2-month checkup formally reviews milestones and includes the first big round of vaccines.
Month two has a famous reward: the social smile. Somewhere around 6 to 8 weeks, many babies begin smiling at you, not just in their sleep, and the feeding-soothing loop starts paying back interest.
This is also, for many families, the hardest crying stretch. Crying commonly peaks around 6 to 8 weeks before it starts to fade, so if evenings are loud right now, you are not doing anything wrong and it does get better.
Development at 2 months
The CDC's 2-month checklist includes smiling when you talk to or smile at the baby, calming when spoken to or picked up, looking at your face, tracking you with their eyes as you move, reacting to loud sounds, and holding the head up when on the tummy.
Cooing starts here too: those first vowel sounds are a conversation invitation. Answer them; back-and-forth is exactly how language starts.
- Social: calms down when spoken to or picked up; looks at your face; seems happy to see you when you walk up; smiles when you talk to or smile at them
- Communication: makes sounds other than crying, reacts to loud sounds
- Thinking: watches you as you move, looks at a toy for several seconds
- Movement: holds head up when on the tummy, moves both arms and both legs, opens hands briefly
Sleep at 2 months
Total sleep still lands around 14 to 17 hours per day, but structure is slowly forming: many babies begin giving one longer stretch of night sleep, often at the start of the night. Wake windows for many 2-month-olds run roughly 60 to 90 minutes.
A simple, repeatable wind-down before sleep (feed, fresh diaper, dim room, steady sound, crib) starts building sleep cues now, even though a strict schedule is still months away. Safe sleep rules stay exactly the same: back to sleep, firm flat empty surface, room-sharing without bed-sharing.
Feeding at 2 months
Feeds may become slightly more efficient and slightly less frequent than in month one, though 8 or more feeds a day is still common for breastfed babies. Growth spurts can temporarily reset the counter and make a baby feed like a newborn again for a day or two.
Keep judging by output and growth: steady diapers and a weight curve your pediatrician is happy with beat any feeding-interval rule.
The crying peak, and getting through it
If there is one thing to know about 2 months, it is that crying normally peaks around now. The pattern even has a name, PURPLE crying, coined to describe the peak, the unexpectedness, the resistance to soothing, the pain-like face, the long bouts and the evening clustering that are all part of normal infant crying.
Layer your soothing tools: motion, sucking, a dim calm room, steady sound. Growbaby's adaptive soothing engine automates the sound layer, reacting to crying in real time and fading out as your baby settles, so one of your hands is effectively free again. And the safety valve stays the same: if you are at your limit, a safe crib and a five-minute break is good parenting, not a failure.
The 2-month checkup
The 2-month visit reviews milestones, growth and feeding, and includes the first major round of vaccinations. Bring your questions written down, sleep deprivation eats lists, and mention anything from the milestone checklist your baby is not doing yet, such as not reacting to loud sounds or not watching faces.
Week by week, in the app
One thing to notice and one thing to try, for every week of the first three years. Here is what this month covers. The app works out which week your child is in from their birth date and brings each one to you on the day.
- Week 5Your baby is Lifting Their Head
- Week 6Your baby is Showing a Social Smile
- Week 7Your baby is Discovering Their Hands
- Week 8Your baby is Making Sounds (Cooing)
- Week 9Your baby is Tracking Objects with Their Head

This week, for your baby
Growbaby works out which week your baby is in from their birth date and brings that week's activity to you on the day, so you are not looking up where you are. Plus adaptive soothing for the nights and Growy for the questions in between.
Frequently asked questions
Around 14 to 17 hours in 24 hours is typical, usually as 4 to 6 naps plus night sleep that may include one longer stretch. Big variation between babies is still completely normal at this age.
Reflex smiles happen from birth, but the social smile, smiling back at you, typically appears around 6 to 8 weeks. If your baby is not smiling socially by the end of month three, mention it to your pediatrician.
Crying normally peaks around 6 to 8 weeks, and evening clustering is part of the normal pattern. It fades over the following weeks. Call your pediatrician if crying comes with fever, feeding refusal, vomiting or unusual lethargy.
Roughly 60 to 90 minutes is a common range at this age. Sleepy cues (zoning out, fussing, rubbing the face on you) are more reliable than any fixed number.
