There are normally little drop down tags that screw on to the legs at the top so that when you lift the side up it runs over these tags which then drop down to keep the side up.

Disengaging the 'drop-side' is the tricky part.
You'd need a size 4 allen key. Assembly instructions will help you locate the screws: http://help.mothercare.com/resources/mothercare/products/Ashton_Cot_Dropside_UPDATE
Before you begin removing screws, you must first disengage the lower part of the 'drop-side'.
At a point midway between the "High" and "Low" postions - the lower side should be pulled outwards (towards yourself). Now lower the 'drop-side' - to release free. It would have been nice if they had marked this position on a visible edge.
Proceed to removing screws in the reverse order of assembly.

if you can tell me the diameter and lent of the bolts and screws i can forward them on to you for free

fully dismatle the cot, keep all the bits.. Take the two slatted sides to bits and put the base pieces of wood from these to one side.
pull the headboard and footboard (is that whats its called) apart take the feet from the footboard and add to the headboard (they are now the sole head and foot boards) screw the 4 nuts with blanking plates to the top 4 holes on the new head and footboards
take the two long slatted size bases and screw them to the lower holes on the head and footboard put the base brackets (L shapped screws) into the corners put the cot base onto the L shaped screws done

Have attached a copy of my instructions
