My 4-and-a-half month old twins sleep from 10pm to 6 or 7am at the moment. They will be going into their own room in about six weeks and I want to get them into a 7pm bedtime. But I am very nervous about disrupting the great night time sleep arrangement we've got at the moment! They have absolutely no nap pattern in the daytime unfortunately - I just let them nap when they get tired. Again this is because I'm nervous to "force" anything which might disrupt their 8 hour night time stretch. I am the sort of person who really needs a lot of sleep, so I'm beyond thankful that we are doing well at the moment. Any tips would be appreciated! :)
