Hi, I've had 2 litters of singletons, but can't really remember :o
I do remember that they were both like roly-poly lumps of lard at 3 weeks :D
Think it is much harder with a singleton, but Mum does get fed up with them, you just have to be quite hard about seperating them for a couple of hours (not easy when they're all on their own, I know) before trying to feed them. Good Luck!
