For the kids' Christmas presents last year, instead of buying toys, my Mum bought them science classes at the Discovery Center.
Only Peter and Breanna are old enough to take the classes, so while those two are learning all sorts of interesting things, Gabe and Ella and I have fun playing in the Discovery Center.
Sometimes, because I don't have enough kids of my own (sarcasm insert), I bring along a friend for Gabe to play with.
Once the classes are done we usually head to a nearby Chinese buffet. I think this might just be Peter's favorite part of Grammy Day.
