1 baby producing loads of laundry (two will make the cupcake even bigger!)
1 cupcake shaped laundry basket
34 laundry items in matching colours (or non-matching colours for a more rustic result)
1 well working washing machine
Put the laundry in washing machine.
Temperature: 60-95 C' for 2-3 hours
Drying time: 1-2 days (a dryer will make this step way quicker!!)
The Cupcake appears automatically when the baby is not sleeping very much.
