Learn how to attach and use Bloom Bottle Companion Tops with your 6oz Bloom Glass Baby Bottle. Step-by-step setup, compatibility checks, and common mistakes to avoid.
Quick answer
Bloom Bottle Companion Tops are interchangeable add-ons designed to fit your 6oz Bloom Glass Baby Bottle and other narrow-neck bottles. Twist a top onto the bottle until snug, then use it for feeding, storing, or pumping as needed.
Why Companion Tops Matter for Your Glass Bottle Setup
The 6oz Bloom Glass Baby Bottle comes with a slow flow nipple, but as your baby grows or your feeding routines change, you may need different tops for different jobs. Companion Tops let you swap the nipple for a storage lid, a sippy spout, or other attachments without buying a new bottle each time.
This modular approach keeps your glass bottle in rotation for years, which is especially useful if you want to avoid plastic bottles. The tops are sold as a set, so you get multiple options in one purchase.
Compatibility Check Before You Attach
Companion Tops are made for the Bloom Bottle and any narrow neck bottle. Before forcing a top onto a bottle, check that the threads align smoothly. If the top doesn't seat easily, it may not be compatible with that bottle's neck size.
The 6oz Bloom Glass Baby Bottle is narrow-neck, so Companion Tops should fit directly. If you're using a different brand, test with an empty bottle first to avoid spills.
How to Attach and Use Companion Tops: Step by Step
- Start with a clean, dry bottle: Wash and dry your 6oz Bloom Glass Baby Bottle and the Companion Top you plan to use. Check that the bottle's threads are free of debris or dried milk. A clean thread ensures a secure seal and prevents leaks.
- Align the top with the bottle neck: Place the Companion Top onto the bottle opening, matching the threads. Turn clockwise gently until it catches. Don't force it; if it doesn't catch, you may have the wrong top or a misaligned thread.
- Tighten until snug, not overtight: Continue twisting until the top is secure. Avoid over-tightening, which can stress the glass or make the top hard to remove. A snug fit is enough to prevent leaks; overtightening can damage the bottle or top.
- Test for leaks with water: Fill the bottle with a small amount of water, attach the top, and invert it over a sink. If you see drips, remove and reattach the top, checking for cross-threading. Always test a new top with water before using it with breastmilk or formula.
- Use the right top for the job: Switch between feeding, storage, and other tops as needed. Remove and wash the top after each use, especially if switching between breastmilk and formula. Label or separate tops if you use them for different purposes to avoid cross-contamination.
