DD1 is 3.4 and DD2 is 6 months.
They are both tired out and ready for bed by 6.30 each evening. Since the clocks changed it's been a bit later, but they have stll both been down by about 7.30/8pm.
DD2 gets really distressed when she's ready for bed. You have to catch it quick, get her in her PJs and down for a feed (which can be quite a long one at bedtime) and she'll settle till about 11. She sleeps in our room. We co-sleep which works well and no current plans to change it until she is sleeping through. She wakes 2-3 times between 7 and 7. More at the moment because she's teething.
DD1 also gets tired out very quickly, and her usual routine is tea, bath / wash / teeth/ milk and story then sleep. If she's in her bed by about 6.45 she will be asleep by 7 and generally sleep through. If she's not down by 7 she is up and down all evening getting stroppy and grumpy until she settles.
Sorry this is getting long - thanks for reading if you're still with me! 
DH is not usually back from work until after 6.30 so more often than not I am doing bedtimes by myself.
BUT: DD1 is almost putting herself to bed at the moment, often in tears, which is really making me sad.
The baby is at an age where she's easily distracted during a feed, so she needs calm and quiet. I get DD1 washed and in her pjs, give her a beaker of milk and a book to look at, and go into the other room to feed the baby. I promise to come and read as soon as the baby is asleep. DD1 pops in and out a couple of times, disturbing her sister, and getting angry at me for leaving her "on her own". I end up putting the baby down (waaaaaaaaaaaaaaa!), DD1 back in her room where she cries and goes to sleep before I have the chance to go an read her story, give her a cuddle and wind her down for bed.
It's making me so sad, as I think it's a really important time of the day, and as it is, she gets little enough one-to-one time since her sister arrived.
My ideal solution would be for the baby to feed / fall asleep while DD1 is having her story, in DD1's room, then I could put her in the cot, or in our room, and give DD1 a cuddle. But she just won't settle to sleep with DD1 around - she loves her too much, but at the same time she cries because she's tired, and makes it impossible to read a story.
Any suggestions as to how to make bedtime with two a bit less painful? One or other seems doomed to cry themself to sleep. :(
Many thanks (and sorry for mammoth thread!)
