i have been to a few 2nd birthdays and Willow has hers in a month i went to a couple in a playcentre it was called funky monkeys and it caters for children up to age 8 dnt know if you have one local to you or not but they were good as they provide food, and i have also been to one at a house and that was good also, they just had some food played pass the parcel etc and that was fun also.
For Willow we are doing her a small party for her friends about 6 altogether at my flat bit of food and just let them have fun nothing major but i felt quilty not letting her have a little party, then on her birthday we are taking her to colchester zoo just the 3 of us.
