- Prefers faces and high-contrast patterns
- Calms when held or spoken to softly
- Breastfed babies feed 8-12 times in 24 hours.
- Sleeps 14-17 hours per day in short stretches of 2-4 hours.
“Skills such as taking a first step, smiling for the first time, and waving 'bye-bye' are called developmental milestones. Children reach milestones in how they play, learn, speak, act, and move.”

Bottom line
Every baby develops at their own pace. The milestones listed for 1 month old are typical ranges based on CDC and AAP guidelines. If your baby hasn't reached a milestone, it doesn't necessarily mean something is wrong — but talk to your pediatrician if you have concerns.
Trust your instincts. If something feels wrong, reach out to your pediatrician. Worrying about your baby means you care — that is a good thing.
