Newborn: Weeks 1–4

• Physical changes: Your newborn is busy adjusting to the world—expect subtle changes in weight, movement, and alertness. Skin may peel and facial features grow more defined.
• Developmental highlights: Reflexes like gripping, rooting, and startling are strong. Babies love cuddle time and respond to soothing voices and gentle touches.
• Joyful tip: Keep your newborn cozy in ultra-soft essentials designed for sensitive skin.

Infancy: Weeks 5–12

• Physical changes: Watch for weight gain and growing curiosity—your baby might begin to lift their head and kick their legs.
• Developmental highlights: Smiles start to appear, and babies may recognize familiar faces and sounds.
• Joyful tip: Outfit your little one in comfy rompers as they discover the joy of movement.

Smiles & Snuggles: Weeks 13–24

• Physical changes: Rolling over and beginning to sit with support! Chubbier cheeks and first giggles are precious at this stage.
• Developmental highlights: Reaching for toys and exploring with hands and mouth are common. Babies love peek-a-boo and musical toys.
• Joyful tip: Encourage sensory exploration with our soft, safe baby toys and gentle play mats.

On the Move: Weeks 25–36

Wonder & Discovery: Weeks 37–52
