My mum bought me the most gorgeous breastfeeding pyjamas where the top can also be worn just as a nightie. I must say that I wore them most nights after going home as they were easy to BF while co-sleeping and I didn't get cold . I also actually still wear them as they are so nice and soft. They were from Dangerous Curves but I think I got them on eBay. ETA they are called the 2 way PJ.
