Too, how annoying re the oil. Does it get delivered regularly though? Must be such a faff having a heating system relying on it. Hope the estate gets back to you quickly. Does all sound rather posh though - a cottage on land belonging to an Earl?! Get you! 
Ninja, we started Iz on food at about the same time as you're thinking of starting DD - mainly because she grabbed hold of my banana and shoved some in my mouth. She'd also been grabbing at our food for ages, making chewing motions and demanding noises when we ate! If she's ready, she's ready. I think the first thing we officially gave Iz was banana... but we wanted to BLW, not puree. Also thought ick to baby rice!
Scarlet, good luck with your homework. You're incredibly brave and strong to be going through all of this - I hope all your efforts pay off.
Dream, you poor thing. I'm often feeling exhausted with one - I can't imagine how hard it must be for you. However, as everyone keeps saying, this too will pass. I agree with what someone (Too?) said - if you can manage with all three on your own for a bit, so can DH. Even if just for a couple more hours in the morning. Even if it is just taking them all for a walk.
Pet, Iz is sometimes easily distracted, other times not! At a friends the other day, she dangled food off of the high chair, and their dog licked it before any of us could do anything - so we obviously had to take the food off her. She was in tears for ages, despite trying to switch it, distract her, cheer her up etc! I'm going to ignore the possibility of toddler tantrums. Iz will get over this phase and be a complete angel. Obviously. 
Iz is being extra-grumpy today. It looks like a tooth may be on its way through - but then again I've only caught short glimpses as she won't let me look properly. Was supposed to be off to a party tonight but my mum's ill so can't babysit... may go for a bit and take Iz (though it's after her bedtime, but I figure an hour later to bed once in a while can't hurt!)... not sure. Have enjoyed this afternoon though - as my mum was supposed to be here, I had nothing work wise planned, so have just spent Iz's nap cuddling her (too grumpy to be put down) and watching DVDs. Ahhh.. :)
