Arts and crafts!

I just realised that I have never really done arts and crafts/messy play with my 28 month old and now feel extremely guilty! we do colour in occasionally and have lots of water play. I have just spent a small fortune online on lots of arts and crafts things such as paints, playdough etc.

How often would you say that you do these activities with your toddlers? I'm hoping for at least 2 afternoons a week. He loves getting messy so hopefully this will entertain him
