Ha Ha, welcome to the dark side...this is how it starts.
There are so many gorgeous nappies around.
I can't comment on Happy Heinys as I've never had any.
My favorite pockets are upsy daisy nappies and funki nappies and green kids (for sale on nappyzone dot co dot uk)
Have a look at Weenotions and babybufter but I must warn you, you won't be able to resist.
Have fun shopping.
