I have twins and I've also been told it's expensive and sooooo muuuuuuch haaaaaard work. The early months were hard, simply because there was no time for anything other than feeding, changing and bathing, the babies not me. I must have eaten at some point but I don't remember when.
To start with each one took an hour to feed, every other hour, so it was literally feed DD1, wind her, change nappy, lay her down and pick up DD2, feed, wind, change, pick up DD1 and repeat. Then DD2's reflux kicked in, which made feeding a much longer process for her. After about 6 weeks for DD1 and 12weeks for DD2 they were going longer between feeds and it became easier- until they started to crawl. In opposite directions
Oh, and the expensive bit is because you have to spend the money in one go, instead of baby related costs being a few years apart.
Even now people tell me how much harder it is to have twins, usually these are people who have not had twins themselves
. I know another two mothers of twins and they didn't find it a particular problem either.
I don't worry about how much hard work other people tell me it is, I just enjoy my twins
