I think its a great idea. You can make it a really special day for Miss O - such a big girl thing to go and look at schools and then have lunch with Mum and Dad.
FWIW, I will take E out for morning tea somewhere on her non-kindy days when I is at school. I will then sometimes pick I up on E's non-kindy days and she and I will go straight from school for afternoon tea. I think its really important to have one on one time with them - the dynamics certainly change when they're both there.
Just need to work out how I'm going to get that one on one time on a regular basis when #3 is here!
