I asked the nursery staff to put them in their bags
At my girls nursery we hand the invites to the staff and they will make sure they get home - usually put them in their bag and let the parent know on pick up so we can take it out.
Same. Staff sticks them to the entrance door so parent can see it
Ask him who he wants, write the names on the invites and ask staff to give them to the parents. Thats what we used to do xx
I would ask the staff to pass the invite. Kids often take out stuff from their pigeonholes/pegs to play with, so the invitations might not even make it home haha
