Weego Twin Baby Carrier: Very helpful for travelling with twins without a stroller. This carrier can be used from birth and even for premies (4lbs and up), while others aren't really designed for use until they're about 8-12 lbs. It's designed to be used until they're about 16-17lbs each, though you could probably push it to 20lbs a piece since it's pretty well-made. I used it for the first few weeks while they were nice and light, and even walked around with them for hours during the summer. It's lightweight but sturdy, and has great support pads for your shoulders and back. Also, since they hang on the front of you, it lets them stay in your line of sight on your chest and hear your heartbeat, as well as makes it easy to feed both of them. (Most other twin carriers are front and back or, weirdly, on your sides under your armpits.) The pictures attached show how you secure them. Bought for $180, selling for $90. 

Would really love this stuff gone by this weekend. Come and get it!
