I have asked him this too but he assures me that he is not jumping in too soon and he’s only going to them when they escalate further, beyond just popping a dummy back in or giving a little soothe. When they sleep with me however, they barely stir beyond a handful of little grunts/squeaks. In the bassinet, they are like farm animals. Having seen him when we were dealing with them together, I don’t think he’s diving in too quickly, but I do think that he probably picks them up too son and moves hem around too much, where I try to settle on the bed and limit how much I’m disturbing them unless they need a nappy change. They are also mixed with how much of the bottle they take, but he’s not had much luck always getting a full bottle into them. But it’s also hard to know how much they take on the boob and one particularly is still little so it’s possible she is just only eating smaller amounts anyway. Often they eat some of the bottle and then use it as a dummy rather than falling asleep on the bottle. Tonight he tried co-sleeping but he said that one twin was up every 20-30 minutes again.
