My DD will turn 3 in November. She's hit and surpassed all milestones. She's a great eater and a great sleeper. She talks a mile a minute and we have no worries about her ability to learn or retain. Her hearing and speech are normal (but hearing has never been tested). She does not get overwhelmed by lots outside noise or busy places.

My question is specifically about loud noises. If she thinks a loud noise is coming she'll cover her ears.

Examples are: walking down the street and dump truck drives by
- watching lion guard and she knows simba is about to roar
- at a pool with buckets that would fill and then splash over dumping into the bigger pool (the splash was "loud")
- daycare said she did it when a new baby was crying (but has since stopped. Did it just when the baby was.new to the daycare)

She doesn't do it if dh or I raise our voice or if a siren goes by or for loud music or in busy places like a mall or food court.

I plan to ask.our ped at the next appt but was curious for opinions.

Is this just one of her pet peeves and normal or is this a sign of something??
