Warm weather often means more movement, more snacks on the go, and sometimes,more bathroom battles. Constipation can sneak up on kids during the summer, especially when water and fiber intake fall behind. Smoothies are a simple, refreshing way to keep hydration and digestion on track.

These summer smoothie ideas are filled with fiber, prebiotics, and hydration-boosting ingredients to help keep your little one regular. Each recipe serves one and can easily be doubled for siblings or parents.

1. Peach Hydration Smoothie

Ingredients (Serves 1):

  • 1/2 cup frozen peaches

  • 1/2 ripe banana

  • 1/2 cup coconut water

  • 1/4 cup plain Greek yogurt

  • 1 tbsp chia seeds

  • 1 scoop Growing Up Prebiotics

Peaches and banana provide soluble fiber, coconut water supports hydration, and chia seeds help soften stools. Prebiotics add a gentle nudge for gut balance.

2. Watermelon Kiwi Cooler

Ingredients (Serves 1):

  • 1 cup cubed seedless watermelon

  • 1 peeled kiwi

  • 1/4 cup water or coconut water

  • 1 tsp lime juice

  • 1 scoop Growing Up Prebiotics

Watermelon is over 90% water and rich in electrolytes. Kiwi has been shown in studies to support bowel movement frequency and consistency.[1]

3. Pineapple Mint Gut Refresher

Ingredients (Serves 1):

  • 1/2 cup frozen pineapple

  • 1/4 cup cucumber, peeled and chopped

  • 1/4 cup apple juice or water

  • 1 tsp fresh mint

  • 1 scoop Growing Up Prebiotics

Pineapple contains bromelain, a natural enzyme that supports digestion, and cucumber adds hydration. Mint can ease bloating and gas.

4. Berry Oat Smoothie

Ingredients (Serves 1):

  • 1/2 cup frozen mixed berries

  • 2 tbsp oats

  • 1/2 banana

  • 1/2 cup oat milk or dairy milk

  • 1 tbsp ground flaxseed

  • 1 scoop Growing Up Prebiotics

Oats and flax add bulk to stool, while berries provide fiber and antioxidants. The texture is like a creamy milkshake—but far more gut-friendly.

Summary

Smoothies are an easy and delicious way to help your kid stay regular during the summer months. Just one fiber- and prebiotic-rich smoothie per day can make a real difference in digestion and poop consistency. For an extra boost, add Growing Up Prebiotics to any smoothie to support the gut microbiome without changing the flavor.
