Just a quickie oooo-er......
Mars, much as I would absolutely LOVE to come to the christmas meet up, what the hell would I say to DP, "erm..... hi honey, for the past year I've been using an internet chat room and my pals have invited me to London for the weekend, that ok with you? "No, I've never met any of them in my puff, yes, I think they're female, yeah, I'll be staying in their house, no, I don't have references" Seriously, it wouldn't work for me atm. I'm having kittens at going out on Friday and leaving my mum to do the school/nursery pick up, tea and baths. Its a corporate thingy with DP and I have to look good and be ready to go at 3pm and be back around 1.3am and I'm wetting myself already. I'm rubbish at these things. Anyone watching would say I was a pro but its all front really. I quiver with nerves and no self-confidence inside. And I have already written a 2 page list of instructions for my mum because she's never had any kids of her own, never worked in a nursery, doesn't know my kids at all and has never even seen the inside of my house .
Anyway, HM, right. My DTs take an hour only (maybe an extra 15 mins if really tired) because, for me, any more than that interrupts their night. It sounds like a good time of day to nap, I never let mine have any sleep after 3pm (not even a quickie in the car). Could you cut them back a little on their sleep? Maybe give them lunch at 11.30am and a nap at 12.30pm?
The other thing is routine. They can get so easily confused with being allowed to do one thing one night and not another so try to have continuity when they get up at night. Its maybe harder in the short term but it will set up good habits going forward as they will know what happens if they do wake and will begin to understand whats expected of them (i.e. to return to sleep). I never bring mine out of their rooms at night (easier since mine have separate rooms), I don't talk very much, I keep saying things like "you just lost teddy, here he his, you're all tucked up and cosy now" to brainwash them that that is why they were awake.
Personally, I wouldn't offer milk at that time of night, but I'm not saying thats right for you. I do offer water if its really hot or if one of mine has a cold/illness. They can learn habits so quickly. The first night waking that they were offered milk might have felt nice so they might now expect it if and when they wake. By teaching a continuity of what happens in the night they may learn that its not that much fun to be awake and just come round and roll back over again (which is what we all do a thousand times a night).
I'm no expert its just some stuff to try. You might have a few nights worth of complaint from them but it will be worth it.
I fear I'm talking waffle again......
