my son is 4 and he has always been very obsessed with things, that i would not consider 'normal' for a child. He loves cds/dvds,tools,keys but his favourite is hoovers. he sleeps with them , carries pictures with him asks everyone about theirs, talks to the hoovers, he has two toy ones of his own and still wants another one, his favourite is henry hoover, although he is now quite taken with dysons.sometimes it is so bad it drives me to distaction. Am i worrying about nothing?
