Or is it best to always plan nothing?
I don't usually make any plans, but foolishly let myself and DH get excited my last birthday. We tried to plan a fun day out for all of us -- then the children refused to go along with it... Take a sulky 7yo anywhere is just awful, ime. Best I could do was a much reduced outing with just one child.
When might they start to think of it as my special day, instead of just about their own whims at the moment?
