Patient's question:
BB is almost four months old, but she hasn't laughed yet. She rarely shows any expressions. She's quite well-behaved and doesn't cry much. The only time she cries is when she's being potty trained—when her pants are taken off, she starts crying as if she's been hit, shedding a lot of tears. Why is she so afraid of using the bathroom? Is it because she's cold, or is there something uncomfortable with her excretory system?Doctor's answer:
The baby is not mute, our baby just started to laugh out loud when they were four and a half months old. Every baby develops differently, some are early, some are late. Don't worry, just wait a little longer, the baby is almost ready to laugh out loud.
