Well done health, sounds like you've got off to a great start 
Ikwym about kids parties. It was my ds's 7th birthday party last weekend. I must admit I did eat quite a bit of cake and chocolate
but I then stopped when it got to Monday, and even though we've still got leftovers I have ignored them all week. And despite a slightly self destruct weekend, I am another 1/2 lb down.
This weekend I am trialling the no snacking at weekends mod.
