Dr. Brown's Options+ Wide-Neck Glass Baby Bottle Sleeve, 100% Silicone, Blue, BPA Free, 5 oz, 1 pack

We love the Dr Brown's Wide Options Bottle system! There are SO many options with this system! First off you get to pick from 8oz or 5oz Bottle sizes AND Plastic OR Glass! We chose ALL options! Glass bottles also have a super nifty silicone sleeve you can use Another! Another cool thing is the bottles can be used WITH or WITHOUT the vent system! We use the vents at home, and when out and about we use them without the vents! Next, let's talk about nipple flow rates! Dr. Brown's has the widest variety for flow rates available! Preemie size all the way up to a Level 4! There is also a specialty Y cut nipple for thicker liquids! These bottles will follow your little one from Infancy up to toddlerhood because Dr. Brown's also has a Sippy Spout available! You can turn your bottles into a sippy cup by removing the nipple, and adding a sippy spout. One more amazing thing is that you can also add a set of Handles!! You can use the Formula Mixing Pitcher for other purposes too! I personally use one for daily breastmilk, the mixer carefully swirls all the fat back into the milk. I also do the same with frozen breastmilk- I put 3 to 4 bags of thawed milk into the pitcher, and then use the mixer to carefully swirl the fat back into the milk! Another Dr. Brown's item that I rant and rave about is the Milk Spa Bottle Warmer!! This bottle warmer accommodates both narrow and wide neck bottles in plastic and glass! You can warm room temperature, refrigerated and frozen milk! Best thing is that you can also directly put a frozen bag of milk in the warmer! I also LOVE using my Deluxe Bottle Sterilizer! This ensures my little one always has a sterile bottle available - and this sterilizer accommodates narrow AND wide neck bottles!! I cannot wait for Dr. Brown's to release more awesome designs on the Wide Neck Bottles!! Dr. Brown's Baby
