Patient's question:
Hello doctor! My baby is already five months old. When I hold her and she urinates, she often makes a clicking sound when her legs kick forward. I don't know what's going on? Also, is it okay to take X-rays at such a young age?Doctor's answer:
This is normal. The motor development of infants follows a certain pattern, from top to bottom: at 2 months, they can lift their heads when lying prone; at 3 months, they can roll from supine to side-lying position; at 4 months, they can sit with support on their hips; at 5 months, they can stand with support under their armpits; at 6 months, they can roll over; at 7 months, they can crawl; at 8 months, they can sit independently; at 9 months, they can stand with support; between 10-11 months, they can stand independently; after 12 months, they can walk.
