1 year old throwing tantrums.. I hope I’m not alone 😩

I

So just this past week my 14mo has started throwing tantrums. He yells & cries til he can’t catch his breath, I try to calm him & sometimes I walk away. Any advice ?

At first I thought there was something wrong with him(hungry, tired,etc) but once I got all that crossed off the list, I realize he’s just doing it. I will pick him up & talk to him, then he’ll calm down for a minute or 2, then start all over again.

What am I doing wrong 😩😩😩😩😩😩
