We really didnt play any games ay Abby's 1st birthday, but at my nieces and nephews parties we have played:
Balloon Races
Bobs and Statues
Pass the Parcel
Pinatas
Craft stuff- everyone had a party box and crown to decorate with jewels, feathers, sparkles etc (that was my fav! obviously for the older kids)

Hers was at afternoon tea time, so food we had:
Sandwiches
Cup cakes
Chocolate Crackles
Hot finger foods
Fruit platters
crackers/chips/dips
And ofcourse the cake!

Good luck!
