DD is formula fed, but she's not taking the full amounts she's supposed to be taking - so I think we're going to be going a while before she sleeps through... Saying that, last night she went from 10:30pm to 4:30am - I remember this with DS, he didn't just drop the night feed, it got later and later (DD started at 2, then it was 2:30, then 3:30 and now last night 4:30) - the tricky bit was when it got to about 5:30am, and I couldn't get him back to sleep - at least this time round I'm prepared that in about a month's time I'm going to have very early starts to the day with DD 
Found last night hard because DS was having nightmares (apparently they were having a bike race and a big scary tiger was trying to steal the bikes) - so he was up for an hour in the night as well - not at the same time as DD so it was 2 lots of them to deal with (DH managed to sleep through all this!)
DD doesn't seem to want to sleep in her cot, has anyone else got this? She'll sleep in the sling, the car seat, her pram (but only if it's moving, no sneaky pushing for 10 minutes then parking her in the hall for a couple of hours), my arms, our bed, but not hers. I've got her to sleep by cuddling her in our bed, have just relocated her to her cot, but not holding out much hope for this lasting...
Oh, and today I had my first trip without her (not counting times I've just nipped to drop DS at nursery on days DH is working from home, tha'ts less than 5 minutes in the car) - took DS to see Planes. Must say, he seems to really have enjoyed having "mummy time" without his baby sister there. How are other mums of more than one managing their older one's needs?
