Tomorrow is LO's 2nd birthday. As far as children there will be several 3 year olds, a 1 1/2 year old and one older child (around age 6). There's a playground where our pavilion is located in the park that the kids can play in. Does anyone has any suggestions for other games I can have that will actually keep the attention of age 2-3 year olds? I already plan to bring chalk and someone mentioned water balloons, I just wanted a few more opinions.
