25 Summer Activities for Nannies (Katy Edition)

The weeks between camps are where summer gets long. Whether you're a nanny, a grandparent on duty, or a parent home for the week, here's a go-to list of activities that keep kids busy without a big budget or a lot of prep.

Nannies & families: if you're juggling camp weeks around your activity days, plan the whole summer on Campella so everyone knows which weeks are camp and which are "at home" days.

Indoor days (when it's 100° or pouring)

  1. Build a fort and read inside it
  2. Kitchen science — baking soda volcanoes, homemade slime
  3. Bake something together and decorate it
  4. Indoor obstacle course with pillows and tape
  5. Themed movie afternoon with a matching craft
  6. LEGO or building challenge with a timer
  7. Learn a card game or a new board game
  8. Kid-led "cooking show" making a simple snack

Get-outside mornings (before it heats up)

  1. Splash pad or neighborhood pool
  2. Early bike ride or scooter loop
  3. Nature scavenger hunt at a local park
  4. Water balloon or sprinkler games in the backyard
  5. Sidewalk chalk mural
  6. Bug and leaf hunt with a magnifying glass
  7. Picnic breakfast outside

Learning that doesn't feel like school

  1. Library visit + summer reading challenge
  2. Start a simple garden pot from seed
  3. Keep a summer journal or comic
  4. Map a "trip" and learn about the places
  5. Simple coding games or typing practice

Field-trip ideas around Katy & Houston

  1. Children's museum morning
  2. Local nature center or preserve
  3. Farmers market treasure hunt
  4. Bowling or an indoor play place on a hot day
  5. Ice cream "taste test" to end the week

Make the weeks flow

The trick to a smooth summer is knowing which weeks are camp weeks and which are activity days — before you're standing in the kitchen at 8 a.m. wondering what's next. Build your family's summer schedule on Campella → and share it so everyone (including the nanny) is on the same page.
