Links to summer activities please!

Hello fellow nannies! I’m still pretty new to nannying (working professionally for a year). Would really appreciate if there are any accounts on social media that have lots of fun activities for the summer. I’m a little worried because I will be home with the kids for 8hrs a day/ 3 days a week in the summer and the shifts feel soooo long. I want to make this summer super fun with them! Stuff we can reuse and whatnot. I’m already on pinterest but if there are any social medial accounts with help, please link them in the comments. If there are any activities you know kids absolutely love or have any hacks, please also list them below.

Kids are ages 2,4, and 6 for one family.
For other family it’s ages 8 and 10.
