Cheer, at around this age we were doing:
Alphabet/colours/shapes/counting - none formally; all through games/songs etc.
Helping in housework - dusting/sorting clothes (esp socks is good for teaching matching)/ putting away toys
Water and sand play - inflatable tub; also used to let him mess about with water in the bathroom (pouring from one cup to another)
Art - crayons/finger paints/water colours, later on colour pencils and a magnetic drawing toy
Songs - the action kind esp.
This last 2 months I've also started on a craft-a-day; thats been great fun. Through all this of course we read ; if she's bored with her baby books get started on stories. If you arent doing it already then start another language (in my case DS is learning the names of everything in English now). Its tough some days but more fun than ever
