Grandma had a great idea which has worked like a charm! She suggested I take an empty water bottle and fill it with some seashells. I have to admit, I had fun making it as it was an excuse to play in the sand and Adam is loving it!! He loves to just shake it around and gets quite a kick out of it! I even ended up making a second one so that I could make seashell music with him! :)
Thanks Grandma for the great idea!
