I'm back after a long break - holiday (went well, with a mixture of travel cots and co-sleeping, but it did mean dp slept in another room :( ) and illness having kept me off regular MN.
nights are as they always were (not great!) and now we're dealing with 5am starts too. the babies are still tired at 5am, but see each other and get too excited to go back to sleep. am going to try blackout blinds but also open to any suggestions - we're already cosleeping by 5am, and they feed then, just don't go back to sleep. grr.
Judys well done! it's a slow process teaching them to sleep on their own, eh? I think my dts have same birthday as yours, as they were just 9 months last Friday too :)
Cosmo, can you shh/pat, but stop when he's calm, then start again when upset? or go from patting to just placing a hand, perhaps by patting progressively more lightly? I have gone from pretty much holding dt1 down (what someone called "firm pressure") and rubbing his back to a still hand, to a light touch, to a hand hovering over his back to (now) no hand at all. all little steps. doesn't mean he wakes less often but last night he did wake and go back to sleep after I came in the room, but without needing to be touched (I normally still use a hand on his back to resettle because I don't want him waking dt1).
Count so sorry you've hit a regression, your ds was doing so well when I was last here. there are two months till September. this are bound to be different by then (as I go back then too, I have to keep believing this).
Sorry, am not fully caught up with everyone, but Bumper 

you give us hope!
