Why does toddler like to scream from time to time? How to handle?

For toddlers in general, screaming is really just an age appropriate way to express themselves. Nothing to worry or sweat small stuff over. Your child is probably excited, bored or just in need of attention. If baby is screaming alot in public or at home, you can try to give baby messages such as "We don't scream in restaurants", or "We do not scream at home". After that, distract baby by offering another option like asking baby to smile, laugh or sing. These are all ways for baby to express excitement without breaking the noise barrier.
