The freebie zorb boosters we got are currently being used to boost night nappies. They seem great, but I have a huuuuuge amount of boosters, so can't justify buying more. And they're needed more in night nappies. I did weigh one of Iris' night nappies recently.
And she pees a lot. She drinks about 1.5 litres during the day (I've just worked out!), so it's a fair amount for one so tiny. And skinny (that's half the problem - too skinny to boost without leg gape).
I have a couple of metres of interlock, so I think I'll make something like those vests. I'll try tucking a regular cotton vest into her longies in the meantime. But I'm not sure a) it'll stay there and b) it won't end up soaked.
Steph - stripping was the first thing I tried. That's why I did stash pics recently; I'd been on a stripping mission. I think you're right about her flooding her nappies, though. I'm just not sure she's ready for potty training. She knows when she's poo'd - if I ask her, she'll run to the bottom of the stairs waiting to go up and be changed. But she certainly doesn't have the language to tell me that she needs to wee/poo. I know I need to buy a potty and try familiarising her with the idea of life beyond nappies ...
Nooooooo!!! I'm just not sure she's quite ready for it.
