Jude7702: Oh how you sound like I did

It does get better I can promise that!! New challenges will arise but it does get "easier." I would say the first 3 months are the hardest? Others may say different though. First off, were they preemie? If so, that makes it all the harder! If not though, then it may not take you 3 months to get your life back! Congrats on getting this far though!!! And you are welcome here any time! Come join us!
I do BabyWise. I did it from the time they got home from the NICU. I do somewhat my own version but it has worked for us. Healthy Sleep Habits, Happy Baby is another one a lot of people like.
First, get them on the same schedule. That will save you. Feed them at the same time, put them down for naps at the same time, baths and bed at the same time. It will be interesting at first but they will get used to it. YOU are in charge, not them! Have the same routine EVERY day. Babies thrive on routine. When I first put them on the same schedule they cried but I knew it had to be done for my sanity. I think mine woke up from 10PM to 1AM for a while but they outgrew that pretty fast. Mine had to be fed every three hours when they got home from NICU.
As far as fussy, do they have colic or are they gassy? that will make them uncomfortable so you need to work with that as well. I use Gripe Water for mine when they are gassy as the Mylacon (sp) drops work but it made mine constipated.
Are you BFing or formula? Some formula will not agree with them so look for signs of that as well. If you are BFing there are women on here that did that solely so they can offer you support there.
Ummm, I would say do not let them nap anywhere. You need to put them in their crib, bassinet, or wherever you are making them sleep at night. That will be hard to break when they are older (trust me, I know!)
Is your husband able to help? If so, you feed them the first shift of the night then him the next so you are both at least getting 6 hours of sleep. If you are BFing, make him bring you the babies. To me, he should not get out of this but that is just me!
When they sleep YOU SLEEP! No joke!! Who cares if your house is a mess or things need to get done. They sleep, you sleep! I did this up until they were like 6 months old. My house is a wreck but I do not care anymore. If people offer help, tell them to wash bottles, do laundry, or whatever. Have people come over to watch the babies while you take a nap.
Ok I wrote a book. We are here to help and please keep us updated!!!
Congrats again!! Twins are the best!
