Dr. Brown’s Natural Flow® Anti-Colic Options+™ Narrow Bottle to Sippy Gift Set with Soft Silicone Sippy Spout, Removable Silicone Handles, Travel Cap and Bottle Brush

We tried Tomme Tippe and other brands bottles but both my boys preferred this one. Nothing can beat Dr. Brown.

The bottles leak, ALL THE TIME. Not just if it falls sideways in your bag, but when you’re actually doing a feed, which means you have spilled milk on you and baby, which is sticky and a mess, and you can’t properly know what you fed because so much has spilled!I’ve read and tried the tips in forums (don’t screw the cap too tight) but it doesn’t really help. And why make a product where users have to guess how tightly or not to screw on the cap? Product failure.The travel cap and lid accessories are also failures. If you use the lid (the small flat piece that looks like a coin), it’s really fidgety to get out. You have to use your finger or a toothpick to try to pop it out when you want to use the bottle, which defeats the purpose of sterilizing. And, it would be milky and slippery from the milk in the bottle, which means again your hands are getting messy and sticky. If you use the travel cap, it doesn’t fit with the green vent in the bottle - so you have to travel with the green vent and the teat/top separate. Makes sense the teat/top would be separate and I’m not as worried about cleanliness there because it has a cap, but the green vent? Just…throw it in your bag? The whole thing just doesn’t make any sense.I wish I could return it. Waste of time and money and unfortunately, just lots of frustration.
