I've been looking after a friends bub for the last few weeks coz she's gone back to work but I don't want to do it anymore. I'm pregnant again and finding it really hard to get a rest when DS is asleep because her bub is really sooky during nap time and well most of the day. Her bub is teaching DS bad sleeping habits coz he used to go to sleep so easily but now he's started being really sooky too. I'm happy to keep doing it until she finds somewhere else but I need to know there is an end. I can't do it any more, it's draining me. How do I tell her I don't want to do it anymore without hurting her feelings?
