Thank you all for your replies. I feel a lot better having discussed it here and with the breeder. She has raised several dogs, some litter mates some parent and child. I realise the work will be extra as well as the cost and am fully prepared to take this on. We are well aquainted with expensive vet bills as our last baby was ill for quite some time and uninsured. This time we won't make that mistake. I live with my parents and my dad is not working just now so he will be with them most of the day. I intend to take one in my room and they will take the other and will make sure to do as much as possible seperately to try to avoid the seperation anxiety. Our last yorkie was as small as these two so the house and garden is still pretty puppy proof. Chaos is about to descend and I can't wait
