Co-sleeping families: Please tell me your bedtime routines!

[GoodnightStars]

DS is nearly 18 months old, we co-sleep (cot in sidecar arrangement) and bf to sleep. The last few days his sleep has gone up the spout and we're struggling to establish a bedtime routine. To date the routine has been roughly:
530 dinner
6 bath
630 into pjs in living room then play
7 read books
730 to bed.
He is now refusing bed and we can't settle him till 930ish!

Any advice/experiences on routines would be great. I have asked particularly for co-sleepers' input as DS doesn't have a 'bedroom' as such to wind him down in.

MrsTuppence yes, thinking about it his manic evening behaviour sounds like overtiredness. I am loathe to encourage DS to drop his nap as surely, like Artandco says, he must still need it at 18 months??

Thanks Tarnishd, think you're right about shortening the schedule and cutting tv.

Andcake DS also stopped 2 naps early - about 8 months I think. That's odd about how the accumulation of 2/3 days without naps your DS will sleep through but I guess it's just his pattern! I think mine may be heading the same way as...he is now in bed beside me fast asleep!

Tried bringing him to bed at 6 - refused. Then of his own accord came to bed for breastfeed at 630 and out like a light! (Btw, am in bed too as currently full of cold and snot).

Thanks for posting your routines, it's really helpful seeing how other families do things .

Sorry - just seen this - she wakes up between 7.30-8am, but I am a SAHM so we don't have anywhere to be particularly
