Aggressive baby

Anyone else 1 year old can go from loving to aggressive. Like my baby can be so mean when she wants something or don’t want you to touch something. Like I had my laptop and she said don’t touch, move then started screaming till she got her way. Idk if I should be worried about this or normal toddler behavior. Like if you have one of her crayons she will snatch it away and say ahhh or say no. She is an o lay child but plays really good with other kids. Idk why she acts so aggressive sometimes but most times she is so lovely and caring and wants cuddles and laughing. Just sometimes I’m concerned about the aggressive especially since she never sees it. She is really smart and can say so many things and knows what a lot of stuff means. Anyone else deal with something like this? Also I don’t spank she is only one just turn one in July also I will not spank her
