Why does my baby cry when I sit down but stop when I stand?

Your baby is probably reacting to the transport response: a built-in calming reflex that turns on when a caregiver stands, shifts, or walks with them. Babies often quiet down because movement, snug body contact, and balance input help their nervous system settle.

Why it happens:

• Motion: Standing usually leads to subtle swaying or walking, which soothes babies.
• Close hold: You naturally hold them more securely when you’re upright.
• Safety cue: Babies are wired to relax during transport, not when they’re still and separated from movement.

What to try:

• Sit on an exercise ball and gently bounce.
• Use a baby carrier or wrap.
• Sit down slowly while keeping the baby snug and moving a little.

If crying is intense, sudden, or comes with fever, poor feeding, vomiting, or unusual sleepiness, check with your pediatrician.
