These were both ordered by a girl in work.
Each one uses:
x56 size 3 Pampers, vest, sleepsuit, trousers, jacket (all 3-6 months), bib, socks, muslin squares, teddy and a fleece blanket.
I always make them with larger nappies and clothes as newborns always have LOADS of clothes, plus I'd imagine mum would like to keep this up for as long as possible without worrying it's all going to get too small!!!!
The boy cake also has baby oil, bath & lotion, booties and bath thermometer.
The boy socks are made into candles and the girl ones into roses (I'm no gardener!)
I also make 'Ingredients' cards to go with them so mum knows what's in it.
