I opted to get rid of my old highchair in favor of two of these :https://www.toysrus.ca/product/index.jsp?productId=4439858
I hate how big highchairs are and since I need two it just wasn't going to happen in my kitchen. The kind I got sits on an existing chair, has a tray for when you want it, you can use the table when they get a bit older and ultimately just use it as a booster seat by taking the back off. I can also use it on the floor for feeding informally if wanted. So that being said..
1. I know that at least initially when feeding DD I used to recline her slightly and I can't tell if that one allows for that.
2. It would be awesomely easy to take with you to a friend's house.
3. Not sure of the weight restrictions on that, you will likely have to also buy a booster seat but they don't cost much.
4. Highchair or not you will find food in every nook and cranny, sometimes days after. lol Kids are messy!
5. You would have to be deligent to check the clamps regularly but that's not really a big deal.
6. The swivel will be great from 6-12months since you would want to face then baby while feeding them. After about a year they start to self feed for the mostpart though.
Opinion: If you couldn't do a booster style highchair then I think this is a great option to save space.
And yes babies can sit on their own by 6 months when they start solids.
Nypage - DD didn't want her old costumes. I was told they were crappy. lol She tried to suck up to Daddy but after waking him he wasn't having any of that. So it was put to her by the two of us. Accept the terms of the contract negotiated the night prior (wear home to show daddy then put away until Halloween) or we would have to return the dress. She reluctantly agreed but also decided we should put it in our closet but it was to tempting. Too funny.
As for the tandem stroller, both seats can come completely off and be traded so I could stitch in a little embroidered patch or something to individualize.. could be the same with their matching car seats and even a side by side stroller too. Great idea.
For those who like giving opinions, here are links to the two strollers I'm thinking of: https://www.babyjogger.com/city_select_lp.aspx and https://mountainbuggy.com/en/buggies/double/duet I totally just don't know which one to get.

My husband helped me get that sucker on today but he can't very well go into the ladies room with me at the shower?! I may have to con my cousin into doing it. 
This weeks appointment I'm going to ask for a shower chair script and pelvic pillow script with hopes the insurance will cover those as well. It'll be nice to sit in the shower without getting stuck. 
You won't have the time nor will you have the energy to do so. My advice is if your unsure you'll get milk in, either have your mom wait on that purchase OR rent a hospital grade pump when you get home. The LAST THING you'll want to do is hand express. Maybe if you had only a singleton but twins is much more invasive. Remember, in the beginning the twins won't drink as much. If your planning to solely bf'd it would be wise to get a pump to pump a bit more each day than the twins will take so that you'll have more milk coming when they have growth spurts AND for when you'd like to store some to bottle feed later on while your not around. In my opinion the pump will be used quite a bit for you. You have TWICE the need for more milk than those of us with singletons who could possibly hand express each breast to keep the supply going. That's my opinion of course.
