It took a little while of getting them used to individual feeding before they got better at not crying whilst they waited. Maybe a week or two of stopping all attempts at tandem feeding and things improved. They slept well during the day in their own cots but only if their twin was also put down to sleep and they could see each other. I also used dummies because I couldn't feed them both to sleep. Mine slept together in one cot until they were about 3 months old so I thought it would be hard separating them but as long as they could see each other they were fine.

I think I breastfed almost non stop for the first 12 months but it does get easier. It was much easier once I stopped tandem feeds as my attachment was better and I could multi task (answer the door, cook the dinner) whilst feeding. I tried a ring sling for a while but couldn't get the hang of it, but I saw a lady the other day with a back baby carrier for one twin and the other in her arms which was obviously a lot of weight on her and no free hands but it kept both twins happy (they were older twins, maybe 6 month or so).
