Well today I've had my first overblown tantrum from a DCK. I just feel like sharing it and see what you guys think. As you know ... you are my only colleagues I think I did ok and I don't really have any concerns other than I hope this doesn't turn out into a tantrum phase

So this almost 2.5 year old girl has been with me for 7 months now. She's very smart, kind and adorable. Lately however she has been having issues following simple instructions like cleanup time, sharing and she's being intentionally messy at lunch time like pouring out her milk and shredding her food with her fingers. Of course here there is always a consequence. I think this little girl was also very tired today which did not help. Anyway so it started while we were outside when it was time to go back in she kept just saying No but still came to the door however very slowly. I ignored it as she was still doing as she was instructed. Then at lunch time I had to take her cup away as she started playing with it. After a few minutes and quick ''Will you be drinking like a big girl now ?'' She got her cup back only to get milk everywhere as she decided to play with it again. So I took it away and told her she would be getting Sippy cups from now on until she could drink better. I also pushed her booster chair away from the table as she was mostly focused on screaming/playing with her friends than eating. At cleanup time she started yelling 'NO NO NO'' and stomping her feet on the floor...Like a full blown tantrum. Never got this from this child yet and this is part of our regular routine so it came to no surprise to her. I told her if she wanted to participate at our story time she would need to help us or she would go straight to her matt. The tantrum continued so she went to her matt and she was forcing herself crying/screaming and coughing. When it was time for everyone else to go to sleep I tucked her in and asked her to calm down and try to be quiet as her friends needed to sleep. She fell asleep after 5 minutes. I have been giving her a lot of timeouts / consequences lately as she often refuses to cooperate or takes toys away from friends after multiple warnings. She is able to make amends when she needs to usually. I am just wondering, is this a phase ? Could it be more ? How would you prevent this from blowing up more every day ?

Thanks for your feedback as always !
