My boy/girl twins turned 2 last month. I used a front/back Snugli for my daughter when she was little (now 6), and I liked it, but I had given it away. I bought 2 front/back Snugli carriers for my twins and found several combinations for them. When they were little, I could wear them both on the front criss crossing the straps and clipping them to opposite sides. It took some playing with at first, but it worked well, was comfortable, and perfectly secure. When they got bigger, I could do the same thing on my back with both, only I needed help to get them "set up." It was harder on my body to carry them both on my back, but it was very comfortable to carry one in front and one in back. I messed around with a Maximom Twin that a friend had and I really didn't like anything about it. I spent about $35 on each of my Snugli carriers and was happy with them. Personally, I didn't get more use than what I spent out of them. It seemed like a good idea, but more often than not, one wanted in and one wanted out or both just didn't like being carried around that way. I did breastfeed them for a year, and there were times when they were on the front that I could literally walk around nursing them and no one had a clue, so that was an unexpected perk. My advice in general is that there are so many things you can do with twins that you figure out along the way, and if you have all the gadgets...great, but you'll probably run out of time to use them all anyway! Congratulations and good luck!
