My son just turned 7 months and recently he has been balling his fist and holding his breath shaking, making a pushing sound as his face gets red. Most of the times he does it if I take a toy away from him or if he grabs something he isn’t supposed to and sometimes he just does it randomly. Is it normal or to young to be doing that or should I bring it to my pediatricians attention? because I’ve read that the temper tantrums don’t start till about 12 months so that’s why I’m a bit more worried and everyone that sees my baby do this comments about “anger issues”.
