By the time your baby reaches 5 months old, you’ll likely notice big changes in their physical skills, communication, and personality. They’re becoming more alert, active, and interactive — and you’re starting to see glimpses of the little person they’re becoming.
Physical Development and Growth
- Weight and Length: Many babies at this stage weigh between 12–18 pounds and measure about 24–27 inches, though growth varies.
- Motor Skills:
- Stronger neck and head control.
- Rolling from tummy to back and possibly from back to tummy.
- Pushing up on arms during tummy time.
- Grabbing and holding toys more intentionally.
- Core Strength: Your baby may begin to sit with support (like a pillow or your lap).
Feeding at 5 Months
- Breastfeeding or Formula: Still the main source of nutrition. Most babies feed every 3–4 hours.
- Solid Foods: Many parents start solids around 6 months, but some may get the go-ahead from a pediatrician at this stage. If so, begin with iron-rich single-ingredient purees and watch for readiness signs: good head control, sitting with support, and showing interest in food.
Sleep Patterns
- Babies at this age often sleep 12–15 hours in a 24-hour period, including 2–3 naps.
- Night sleep stretches may be longer — sometimes 6–8 hours — but waking at night is still common.
Cognitive and Social Development
- Exploration: Babies love putting things in their mouth to learn about texture and shape (so keep choking hazards away).
- Vision: Clearer eyesight allows them to track moving objects and recognize familiar faces from a distance.
- Social Interaction: They may smile more readily, laugh, and engage in “conversations” with coos, squeals, and babbling.
- Object Awareness: Beginning to understand cause and effect, like shaking a rattle to make noise.
Tips for Supporting Development
- Tummy Time: Continue daily tummy time to strengthen neck, arm, and back muscles.
- Play: Offer colorful, lightweight toys, rattles, and soft books.
- Talk and Sing: Narrating your day and singing songs supports language skills.
- Safe Environment: Baby-proof your home as rolling and scooting may start suddenly.
When to Call the Pediatrician
Every baby develops at their own pace, but check in with your doctor if your 5-month-old:
- Isn’t showing any interest in holding objects.
- Has poor head control.
- Doesn’t respond to loud sounds or your voice.
- Shows no social smiles or interaction.
Key Takeaway:
Your 5-month-old is becoming more physically capable, socially responsive, and curious. Consistent care, plenty of interaction, and a safe, stimulating environment will help your baby thrive as they head toward the exciting 6-month milestone.
