Do you think your babies are eating the worms yet? Mine go nuts now when I put them in!
They're doing well thanks, they look like tiny little corys now. I moved them into the breeder box this morning after putting a stocking over it like you suggested. I can see them better now as they're lower in the tank and the side of the box is transparent (apart from the stocking) instead of translucent like the tub. That means that the tetras can see them too, and they're skulking around underneath the box watching them. They have a bit more growing to do yet before they go in the tank!
I gave them a pellet earlier and some crushed up flake a bit ago, I'll see how they get on with it.
