Hi!
I know all about this my lovely as I trained as a nursery nurse on the NNEB and one of my placements was a chilmionder (who was sooooo lovely, and taught me so much!)
you dont pay her if shes a student trainee, however, nice biscuits for tea breaks certainly won me over!
Get her to do not just fun things but the mundane tasks too, alot of students dont like it, but there are dull parts to every career.
always supervise her, never leave her unattended even if she seems like super mary poppins she/he is still in training.
The student will probably have to do observations, make sure they ask/ you ask parental permission before hand and that the childs mane isnt included in the obs she submits (also ask to see it)
students are great assistants, I went to my placement every friday and loved it!
(my other placements were the childrens ward, the maternity ward, a primary school and a nursery.)
Good luck!
p.s. get your request in to the colege asap, as the new students wil strat sept and are prob already registered!
