Why does my baby grunt?
Grunting is often just digestion — babies learning to pass gas or stool. If it's with every breath or accompanied by flaring nostrils, contact your pediatrician.
When do babies roll over?
Most babies roll from tummy to back around 4-5 months. Each child develops uniquely; talk to your doctor if no rolling by 6 months.
Sleep regressions explained
Common around 4, 8-10, 12, and 18 months. Often linked to developmental leaps. Stick to routines and consider white noise.
