Learn step-by-step how to transition your baby from bottle to sippy cup, including tips for using a 4-in-1 transition cup like the Küp.

Quick Answer

Start by replacing one bottle feeding a day with a sippy cup, using a soft spout or straw, and gradually increase as your baby gets the hang of it.

Why a Gradual Transition Works Best

Switching from bottle to sippy cup is a big change for your baby. A gradual approach lets them get used to the new cup without feeling rushed or frustrated. Start with one feeding a day, then slowly add more as they become comfortable.

Every baby is different. Some take to a sippy cup quickly, while others need more time. Watch your baby's cues and adjust the pace accordingly. If they resist, take a break and try again in a few days.

Choosing the Right Cup for Your Baby

The right cup can make all the difference. Look for a cup that grows with your child, so you don't have to buy multiple cups as they develop. A 4-in-1 transition cup offers different modes—spout, straw, and open cup—so you can switch as your baby's skills improve.

Spill-proof features are handy for mess-free practice, but remember that open-cup practice is important for developing mature drinking skills. A cup with a removable valve can give you both options.

Step-by-Step Transition Guide

Start with one feeding a day: Replace one daytime bottle feeding with a sippy cup, preferably when your baby is calm and not too hungry. If your baby refuses, try offering the cup before the bottle when they're more willing to experiment.
Use the spout or straw mode: Begin with the soft spout or straw mode on a transition cup to make the change easier for your baby. Watch for leaks—make sure the valve is properly inserted to avoid spills.
Gradually increase the number of sippy cup feedings: Over the next few weeks, replace more bottle feedings with the sippy cup until your baby is using it for all feeds. Keep the bottle out of sight to reduce confusion and encourage the switch.
Practice open-cup skills: Once your baby is comfortable with the spout or straw, start offering the open-cup mode during meals, holding the cup for them if needed. Expect spills—it's a normal part of learning. Use a bib or placemat to make cleanup easier.
Phase out the bottle completely: By around 12 months, aim to have your baby using the sippy cup for all drinks, and remove bottles from the routine. If your baby still wants the bottle at bedtime, replace it with a cup of water or a comforting routine instead.
