Having a webpage is a great marketing tool for a home daycare. I don't see any cons about it. When I did mine I googled several home daycare webpages to get ideas of how to make mine. You can check webpages in daycare bear from other providers that are posting their website in their adds... The only thing I would recommend is not to make it similar to any of the providers in your area. You both could end up looking silly if parents find similar webpages from the same area and not taking you seriously... I've seen this in my area before and it's hard to know who is the real deal and doesn't look professional either.
