Sippy Cup Conversion Kit Compatible with Philips Avent Natural Baby Bottle - Weighted Straw, Silicone Spout Nipple, Handles & Brush - Spill Proof Transition Trainer Set for Self Feeding (Pack of 2)

These fit perfectly on our advent bottles. It is a good first step for trying to move our baby from a bottle.

These are absolutely amazing! They are a perfect fit for our Phillips advent bottles. They converted the bottles easily into a sippy cup. It’s not a bad price for 2, and they work very well. They don’t leak from what I can see, we have used the quite a bit since getting them.

I like the design. Easyvto use and drink through. It fits my glass avent bottles fine. Haven't had any leaking issues. Simple enough to clean with proper tools.

Fits wide mouth bottles. Worked great for my daughters avent bottles. The cool thing about this set up is that the liquid fills up the nipple part and they dont need to suck so hard. It can cause leaks.

What a great idea, to use a bottle you already have and can change it a little as your little one grows. This has helped my little one in learning how to independently feed and hold their bottle during the day. I recommend Philip Advent bottles all the time and this is just one more thing I can add to tell them about!

Functionality is sub par ; Took off the straw part as it’s sometimes a hassle when u pour juice with pulp for example I will squeeze a lime or lemon in the water and the straw gets clogged. Overall the product is ok it’s durable, doesn’t leak and the handles are useful for baby to hold.

Fits on the Philip avent natural bottles no problem. Glad it came with a cleaning brush because my others would not fit in the weight. Easy to clean. We've been struggling to wean my 1.5 year old off the bottle at night and this has been a good compromise - she takes it with no complaints.

I have recommended these to every mom. Great sippy cup for all ages! The weighted bit at the bottom of the flexed straw always they to tilt the drink all the way up and still be able to drink bc it falls with gravity. Easy to use, easy to hold, 10/10 would recommend!
