Phew, bigboobs, you are back, unscathed from taking your three out and did well!!!
I find it depends what the 'out' is as to how stressful/fun it is. Soft play with dh and I is lovely if one baby is asleep or awake and calm in the buggy (only ever dt2 for the latter part...). If both are awake and hungry/screaming I struggle by myself out, especially somewhere like that. If it's a playgroup, it's fine, as I only go to ones where I know at least one or to people quite happy to hold a twin. Friends' houses, ditto, easy enough. shopping/ cafe/ park etc are harder though, for same reason that if DD isn't occupied (or even if she is if dh/dm/mothers help there) and more than one baby awake it can quickly becme a multiple screaming disaster.
Can I ask, those with twins and a toddler, how much crying is there when its just you and them?? Minutes or hours at a time? My dt1 will actually not sit in a bouncer chair or lie on a playmat for more than 5 minutes, 10 minutes tops without screaming. A lot of screaming, tears running down face and getting to the hysterical stage were even once 'rescued' and picked up and comforted his breathing can take a while to settle down from that gulping, 'I've been sobbing my heart out' kind of breathing iykwim. DT2 will sit for longer, but needs holding up after feeds for a bit ideally, so gets very upset too if put down after them too quickly and also will only sit for so long, as expected of a 17 week old baby... So when its just me, there is almost never not a baby screaming, which I find really stressful and hard to deal with. I tend to take to the buggy... For example: By 9am yesterday we were on our way to the river to feed the ducks. Safe I thought, 2 tired babies, up since 6:30, they'll sleep in the buggy, I'll have a good 60-90 minutes peace, we'll get back, feed again, DD will have been out so be happier inside again, lovely. What actually happened was go past (abandoned Travellers) pony, feed carrots we'd brought, get to river, feed ducks bread we'd brought, DT1 wake up, 'fine' I think, no problem, dt2 wake up- both howling... Feed dt1, DD refuse to listen and stay safely in my arms reach and instead arse around trying to stroke ducks ( 
) too close to the river so imprison her in the buggy, Swap to comfort/feed dt2, dt1 screaming his head off in the buggy, random fishermen moving away, getting funny looks from dogwalkers, DD whinging to get down, put Dt2 back in buggy, dt1 and dt2 screaming, dd whinging. Get DD out, she doesn't listen again (a lot to expect from a nearly 23 month old anyway, I know) and off she heads back to the ducks, catch her, re-imprison, get phone call from my dad to say he's come up after all and is at the house so a 15 minute walk from me, breath a sigh of relief and await reinforcements while holding dt1, rocking dt2 and distracting DD wwith duck-chat.... Even at home I struggle though, as I can't get the dts to sleep in the day without buggy-ing them, so can push them around in the garden a bit, but DD still needs so much watching (she was trying to eat berries the other day- serious constant supervision needed!) so it's just really hard. Where am I going wrong here? Any suggestions as to why I'm struggling soo much? I'm still not confident with all three so feeling pretty rubbish about that 
. Had to hand DT1 over to dh at 1:30am after his 5th wake-up of the night to avoid chucking him out of the window in frustration and exhaustion... Luckily dh got him down and he slept til 4am- miracle for him these days. He's such a rattly chest though, praying thats why its so bad atm... DT2 is showing huge improvement and only woke once at 4:30 
. I hope they don't understand tweleve, I've been telling him he's such a good sleeper he's my favourite twin!! 
Also twelve I love the description of feeding dts as like 'wrestling a ferret' 
. He sounds fantastic, if hard work by himself, never mind two of them. I am so impressed that he is doing just everything, but everything physically he should so early for being so prem too. For both of them- your DD sounds adorable too. Mine was like that- happy to sit and smile and giggle, although she did want to walk everywhere holding my hands from 8 months onwards, did her first independent steps at 10 months and was well away by 12 months.... (never crawled though, and only learnt that a few weeks ago, and now is actually behind with climbing/crawling/agility stuff...). I love hearing about yours and bb3s girls- aways brings a smile.
Seeing as I always post negative things, I think I'd better add some positive too- my boys are delightful. DT1 may hate to be put down, ever, but he does a good line in baby babble and huge, open mouthed gummy grins. He can now get hands to midline, hands together and can scoot himself under his (third hand, grotty, not washable) toys on his playmat and suck them, vigorously... He's not rolling, but on his back can go 180 degrees iykwim? dt2 is also a lovely babbler, really reminds me of DD at his age- he's aslim build like her, big eyed (like a tarsi!) much more sensitive to loud noises and busy situations, and gets overwhelmed and needs taking somewhere quieter for a bit. DT1 loves bustle, he adores busy playgroups, watching other children, meeting new people. Such different little babies, and very much loved but bloody well stay asleep for longer dt1!!!!!
