What are the current quarantine requirements for families traveling to Thailand during COVID-19?

Hello! Anyone already in Thailand and have gone through the Quarantine stages with a family? My family (including two little ones under 10), have a trip booked for June to August. A few questions for those that may know....thank you in advance for your help. 🙏

1) Are the little ones required to take a covid test?

2) What if we’re vaccinated, is the quarantine still mandatory?

3) is family activities still open? Kids play area inside malls? Floating market? Tourist spots?

*i know this is a long shot and silly questions for some, again, thank you for reading and being patient. And huge thank you if you’re able to help me with the questions* 🙏
