I work in a nursery and it is definitely not easy with 2 year olds! I also have a 2 year old myself. Here are a few things I find work:
Choices: 2 year olds love to feel independent, and so it can often help to give them small but manageable choices. Things like "would you like blue socks or red socks?" Etc.
Negatives in to positives: so "Don't climb up the slide" becomes "Climbing is fun, if you want to climb you could have a turn on the balancing beam" etc.
Labelling emotions; I find this works so well with my 2 year old, although it depends on the child's ability. I often say I my 2 year old "You are cross because you didn't want to hold my hand, it is important to hold hands because the cars are dangerous" or "You look tired, lets have a story" etc. I find my daughter will now say things like "I not happy with you" instead of the screaming which helps to talk and negotiate.
Naps/ snacks: alot of children really still need down the or sleeps at this age, my daughter still often sleeps for 2 hours.. Does your mindee need a sleep or even 20 mins story or TV time just to wind down? I also find this age group ale hunger badly and feeling hungry leads to more paddies.
It depends on the child but also when we first started having real massive tantrums I used to conpletely ignore them. Even in public which was soul destroying, I remember casually browsing fake flowers in wilkinsons whilst my 2 year old lay on the floor kicking and screaming. Alot of dirty looks were thrown my way but she soon learnt that it didn't really achieve much, and critically I think she learnt that being in public wasn't a trigger for me to be embarrassed. After these monster paddies I would carry on our day with lots of praise
The last one is praise and stickers: When having a real blip in behaviour I try to ignore the paddies and focus on every thing that is good behaviour. Literally praising "you are playing nicely" "well done for using your fork" "you put your shoes away, good job" blah blah blah, it's very fake and tedious but is great for toddlers self esteem, and realising good behaviours make a happier day.
Also with the story thing, maybe you could encourage him by saying something like "this story is for hating, but it would help of you could turn the page for me" getting him involved but also feeling important?
Sorry I've rambled lol, hopefully something will work, but if not just remember its a phase like every other phase and it will pass :-)
