Mom advice please !

Snnsjs

I have an 1 year old boy .

He suddenly started to do somethings he has never done .

I am now worried because it’s happening way to often now , I have an appointment with is pediatrician already .

But I just wanted to know if so any one has experienced something similar with there kiddos.

1.My son will scream his lungs out @ any time over and over again .

2. he will start banging his head in his crib , floor , and in his car seat .
