How can I word my baby shower invitation?

At the moment, I can't decide whether it's a morning or afternoon thing... but I'll get there.

We don't have a huge back yard. So mum suggested asking not to bring kids to the baby shower (yet there will probably be my ds, DH's friend - to keep him company - is bringing his little girl, and my niece and nephew...)

also, we wanted to ask no stuffed toys. MIL suggest no toys in general coz DS has heaps.

How would I go about wording these so as not to offend?

MIL suggests a list of things we need so it makes it easier on the guest, but I think that it comes off a bit presumptuous (for lack of a better word).

People might have to bring a chair, coz omg the list is long! How would I put that on there too?

What did your invitation say?
