If you are looking for cheap or free things to do the local libraries are a great place to start. If you stay home with your kids, there is always yoga or story times happening. Many of the libraries also have authors visit.
The Jericho Library has a PJ storytime on Thursday, October 4 at 7pm.
In two weeks, the Plainview-Old Bethpage library is having a craft & gift fair. On October 7 from 10am-6pm. The Plainview-Old Bethpage Chamber of Commerce and the POB Library co-sponsor this family event. Great shopping, live entertainment, inflatable kids rides and food. Free face-painting for all with a donation of non-perishable food or personal care items for LI Cares. Looks like it will be lots of fun.
