Nipple Flow Rates Explained

Ember offers four nipple options for varying ages and flow rates. As babies grow and get stronger, they will become more efficient at feeding and usually that means they need a faster flow rate. For a parent or caregiver feeding a growing baby, it's important to consider the nipple flow rate and stage of each nipple you choose to use. The nipple flow rate will make a difference, and the proper one will allow your baby to feed more efficiently.

It’s important to monitor each feed for signs your baby is ready for the next level. Some signs to watch for, such as taking longer than usual to finish feeding, falling asleep during feeding, or becoming irritated while feeding, will help alert you that it's time to move up to the next nipple size.

Level 1: Low flow rate that is ideal for babies aged 0 months and over.

Level 2: Medium-low flow rate that is ideal for babies aged 3 months and over.

Level 3: Medium-high flow rate that is ideal for babies aged 6 months and over.

Level 4: High flow rate that is ideal for babies aged 9 months and over.

If your baby prefers Philips Avent™ Natural™ nipples or Dr. Brown’s™ Wide Neck nipples, Ember offers collar/ nipple adapters to use².

Pour any remaining contents out before disassembling the body and end cap.

Sanitize the disassembled parts in one of the following ways:

    Frequently Asked Questions

    How long does the Ember Baby Bottle take to heat?

    Once the bottle is filled with breastmilk or formula, the Smart Warming Puck can heat a 6oz baby bottle in under 5 minutes. The exact timing of each warming cycle depends on many factors, such as amount of milk/formula, thickness of milk/formula, initial temperature of milk/formula, ambient temperature of the room, resting time between warming cycles, etc. ¹

    What temperature does the Ember Baby Bottle heat to?

    The Ember Baby Bottle warms to body temperature (approximately 98.6°F). Ember’s patented technology uses triple redundancy protection in the bottle to make sure the liquid temperature is safe. Power will be cut off to the bottle if any of the three protection limit sensors are tripped or the liquid gets too hot. There are also safety circuits to monitor the puck and bottle temperatures and the battery temperature.

    Can I warm the Ember Baby Bottle without the Ember Baby App?

    Yes! Although the Ember Baby App allows for easy warming remotely from your smartphone, you can still warm the bottle without it. With the filled bottle placed on the Smart Puck, you can simply double press the button to begin warming. Without the app, you will not be notified of when the bottle is ready, but you can see the LEDs on the front of the Smart Puck. Five solid orange lights mean it’s ready for drinking!

    How long does the Smart Puck charge last?

    A single charge can provide two full warming cycles. The exact number of cycles depends on many factors, such as amount of milk/formula, thickness of milk/formula, initial temperature of milk/formula, ambient temperature of the room, etc.

    If the bottle is left on the Smart Puck after a full warming, the Smart Puck will keep the milk warm for up to 30 minutes, until powering off the heater.

    In sleep mode, a full charge can last more than 2 months.
