desertcart.com : Thyseed Anti-Colic Glass Baby Bottle for Breastfed Infants, Natural Feeding, Breast-Like Newborn Slow Flow Nipple (1m+), 5 oz, 1 Pack : Baby

## Features

- Anti-colic base vent for fewer bubbles and calmer feeds: Clinically studied and published in JAMA.¹ The base vent helps separate air from milk to reduce bubbles and swallowed air, supporting calmer feeds with less gas and less tummy discomfort.
- Steady, paced flow to help baby feed more comfortably: Multiple micro-openings in the nipple give your baby a smoother, more even flow of milk to help reduce gulping and frustration.
- Ultra-soft silicone for a more natural feel: Flexible, soft silicone moves as baby feeds to support natural tongue movement and a more familiar feeding experience, especially for babies transitioning from breast to bottle.
- Breast-like nipple shape to help baby latch more naturally: Wide base with realistic breast-shaped nipple encourages a deeper and easier latch, reducing stress for baby and parent when switching between breast and bottle.
- Premium, safety-tested materials: Made with high-quality liquid silicone from WACKER (Germany), premium PP from TotalEnergies (France), and food-grade borosilicate glass. BPA-free, odor-resistant, durable, and designed for everyday feeding confidence.
- 6 flow rates designed to grow with baby: Choose the flow that best matches your baby’s feeding stage and comfort level for a more relaxed feeding experience.
- Fewer parts, easier cleaning: Assembly and cleaning are faster and easier, thanks to a simplified design with fewer parts and a wide neck. Dishwasher-safe (top-rack only) components.

## Questions & Answers

**Q: Why do bottles come in glass and PPSU? How to choose?**
A: Both designs are identical, but glass heats milk faster while PPSU is lighter and nearly unbreakable – both are safer with heat than regular plastic bottles.

**Q: What’s borosilicate glass? Is it better?**
A: It’s extra-tough glass that handles sudden temperature changes better than everyday glass, so it’s less likely to crack.

**Q: What’s the warming base pad for?**
A: It seals the bottle base during warming to prevent leaks – just remember to remove it before feeding your baby.

**Q: Why does milk leak when my baby sucks?**
A: Warm liquid can build up pressure inside the bottle, causing milk to flow through the nipple even without sucking. If this happens, unscrew the cap to release pressure, then tighten it before feeding to prevent fast flow, choking, or spills.
