Hi, I’m so sorry to hear you are struggling. My twins are now 16, but reading your post has taken me right back to the first few months which were hellish.
My 2 would tag team and I had very little sleep for the first few months. It got to the point where I felt I would either do something to myself or them. Things had to change.
The thing that really helped me was getting the twins onto a really strict routine, and I mean really strict. I always thought I would do baby led things, but in reality, with twins it was impossible.
My friend gave me a book called the baby whisperer (or something like that) by a woman called Tracey something.
Following her routine saved me. It was E A S Y i.e. Eat, Activity, Sleep You.
The general premise was always to put the child down to sleep when they were awake, and not to rock etc. The reason being that they would associate rocking with sleeping and it would be harder for them to settle themselves without the crutch of being rocked, or fed to sleep.
It was very hard to start with.I would have to keep them awake after a feed for ‘activity’ time and then put them down to sleep. For the first few weeks I had to pat their backs for them to drop off and gradually reduced the patting time. There was quite a bit of crying at this stage. Eventually I was able to put them into their cots and leave the room.
Initially they would only sleep for 20-30 minutes, but at about 9 months it was if a switch had been flicked and they started having proper naps.
I kept the same rigid routine every day (the nap timings altered as they got older and went to one nap). I really think the routine helped them, it certainly helped me.
It was such a horrible time, but it did get better and it will for you. Can you have some time away from them, as in going out for lunch or something? I know you say that they don’t settle as well when they’re with their dad, but if you are not there you won’t hear them.
I remember when I had visitors, they would offer to do housework etc when what I really wanted them to do was to take the twins from me and entertain them so I could do something normal like doing a load of washing!
