My baby is developing a bad temper how can I sort this?

Ra
My son is 9 months old and he is becoming very strong willed. He hates getting put in a car seat, pram, high chair (basically anything that restrains him) and he screams. Even getting him changed and nappy changed is a battle cause he wants down to crawl about and rolls around making it take 10 times longer than it needs to. I understand this is just a baby and part of development. But I'm just wondering is there anything I can do to control his temper a bit or stop it getting any worse. If for example he is holding something and I take it off him he screams.
