How to handle a baby with a very bad temper
I'm not so sure that a baby can have a temper. But having a 6 month old has taught me that they can definitely get pretty upset. There are days I wonder how on earth that kid can scream so loud.
My only reaction, which is extremely difficult but necessary, is no reaction at all. I swaddle him up, I sit in our glider and I rock him until he's calm. Sometimes it's just for a minute, sometimes it will go on for a good half hour. It's tough. There is nothing simple about it, but it's good practice for when he's a toddler throwing fits.
Be patient with your child, take a break when you need to. If need be, put baby in the crib and walk away until you can handle the matter safely.
