you can't beat a knitted cardy and hat to keep a newborn baby warm..i used to love wrapping mine up and putting them in their prams (proper pram not buggy ) and taking them out
I knew a woman who used to knit for prem babies when we were on the oncolog ward, I still have a knitted fairy she did for my daughter , it goes on my Christmas tree every year
my gran was a prolific knitter and she used to say " don't buy it , i'll knit you one"
