Buy a large perambulator and take your progeny for a breathe of fresh air.... this must be done routinely and on a regular basis or the all seeing one will become suspicious.
Trips can then be made to retrieve small items ( previously concealed under a hedge or similar ) that can easily be hidden under the childs duvet and smuggled in .... larger items.. such as Eteks.. take up a lot of room and it may mean a temporary swap ...Etek in .....child out.
