Your baby's fourth week: First social smiles, improved head control, and emerging personality
| Feeding Type | Frequency | Amount/Duration | Notes |
|---|---|---|---|
| Breastfeeding | 7-10 times/day | 20-40 minutes | More efficient feeding, may go 3-4 hours between feeds |
| Formula | 6-8 times/day | 3-5 oz per feed | Longer stretches between feeds, especially at night |
Good news: Many babies start to have slightly longer feeding intervals and may sleep for longer stretches at night.
Talk, sing, and make faces to encourage those first smiles. Respond to baby's attempts at communication.
Increase tummy time to 3-5 minutes several times daily to strengthen neck and shoulder muscles.
Start establishing gentle bedtime routines with dimmed lights and calm activities.
Provide gentle stimulation but watch for overstimulation cues and allow quiet time.
Around 6 weeks, another growth spurt is common. Some babies may show early signs around 4-5 weeks.
Prepare for: Increased feeding frequency, more fussiness, and temporary sleep disruption.
Social smiles typically appear between 4-8 weeks. Some babies are just developing at their own pace.
Keep trying: Continue talking, singing, and making eye contact. The smiles will come!
Some babies experience temporary sleep disruption around 4 weeks due to developmental changes.
Stay consistent: Maintain routines and be patient as baby's nervous system develops.
As you approach the one-month mark, your baby will become increasingly interactive and alert. The first month is a huge milestone for both baby and parents!
