Can you get in touch with one of your daughter's pals, I found the young women very helpful. They organised games like guessing the date/weight of the baby, it included large sheets of white paper, coloured felt tips on which to write your guesses. Guess the thing on the nappy, gruesome I know but quite good fun - you can use various condiments and your imagination.
I made life easy by ordered food, sandwiches and finger nibbles from our local supermarket along with crisps and bread sticks. I also ordered a baby shower cake from costco, £10 and they'll do a pram/baby/photograph, whatever you want - it served 20.
I know I was a bit of a lazy gran but having so many bubbling young women plus their toddlers in the house felt like enough without baking and cooking.
Jugs of cordial and some bucks fizz but the baby's father turned up with several bottles of fizz - tea and coffee was well received.
Enjoy it.
