Caring for Your Mubsie Straw Training Cup

A little care keeps your cup clean, leak-free, and safe for your little one. Here's everything you need to know.

✨ Before First Use

Take the cup fully apart: lid, straw, valve, and gravity ball. Wash all parts with warm water and mild soap. Then sterilise them and let them air dry.

♨️ Sterilising Safely

You can sterilise the cup by boiling it or in an electric steam sterilizer. Follow these steps so it keeps its shape:

• Boiling: Use a large pot with plenty of water. Don't let the cup touch the sides or bottom of the pot, because direct contact with hot metal can bend it. Boil for no more than 5 minutes.
• Steam sterilizer: Always add the amount of water your sterilizer's manual says, and never let it run dry. Place all parts on the rack, away from the heating plate.
• Drying: Skip the heat-dry function and let the parts air dry.
• Microwave sterilizers: Not recommended.
• If any part changes shape, stop using it, since a bent lid or cup may leak. Message us on WhatsApp and we'll help.

🧼 Daily Cleaning

• Rinse the cup and straw with water right after use, so milk or juice doesn't dry inside.
• Take the cup apart fully before washing. The straw, valve, and gravity ball can hide leftover liquid.
• Use the included straw brush to clean inside the straw from both ends.
• Wash all parts with warm water and mild soap, rinse well, and let them air dry before putting them back together.

🥤 Learning to Sip

This is a training cup, so the first few tries may take practice. That's normal.

• Show your baby how to sip with a gentle bite. Biting too hard closes the valve and stops the flow.
• If nothing comes out, check that the valve is fitted properly and the straw is clean.
• Most babies get the hang of it within a few days.

🌿 Getting Rid of Smells

Silicone parts can sometimes hold on to smells, especially from milk.

For quicker results:

1. Add 1 teaspoon of baking soda to a bowl of water.
2. Soak the silicone straw and valve in it overnight.
3. Rinse well, then let them air dry in sunlight near a window.

🔄 When to Replace

• Straw and valve: every 3 months, or sooner if your baby is a strong biter
• Cup body: when it cracks, gets deep scratches, or turns cloudy

Your cup comes with a spare straw and gravity ball set, so you're covered for your first replacement.

🔍 Check Before Every Use

Look over the straw and valve before each use. Replace them right away if you notice:

• Bite marks, cuts, or tears
• A sticky or rough surface
• A valve that leaks or won't close properly

🚫 Please Avoid

• Filling with very hot liquids
• Microwaving the cup
• Letting the cup touch the sides of a hot pot or the heating plate of a sterilizer
• Harsh cleaners, bleach, or rough scrubbers
• Letting your baby walk or run while drinking from the cup

Recommended age: 9 months and up. Always supervise your child while drinking.
