Twenty months is still kinda young to not be 'locked & loaded, ' as I say. It could be too much freedom but then agian, she could be the kind who stays right next to the stroller. And right now you might thing she'll stay w/you but that could all change once the baby comes. The stroller one other mom mentioned, if I'm understanding her correctly, is a Phil & Ted's which are VERY pricey. Baby equipment seems to get more & more expensive every year! Maybe a friend has a double stroller you can try out, look in re-sale stores, at Craig's List or on eBay. My girlfriend had a front/back stroller made by Graco & LOVED it. Another friend of mine had the Peg Perago Aria (side by side) & LOVED that. The Peg Perago is pricey, close to $300 new, but I have to say, I liked pushing her's better than my other friend's Graco. The Aria is a smidge narrower than the average side by side but you can still fit an infant seat in it. I've seen the Aria on Craig's List as well as eBay. Hope this helps & good luck!
