Children's Safety

We are considering looking at an old farmhouse to buy if we end up relocating.  It has four acres and they just reduced the price on it.  Unfortunately, it needs a lot of updating.  There's also probably lead paint under the paint layers somewhere so I need to get a lead test kit.  I want one that is EPA approved.  The picture looks like there is a pool on the property so we'll need a swimming pool alarm too.  I want to make sure my kids stay safe no matter where we live.  I'm extra cautious about my kids' safety.  Becoming a mom made me more neurotic than I already was - my poor, overprotected kids.
