Happy birthday Grammie G

Dave has been carrying this sign around with him all day. We've been trying to figure out what it means, but it's so mysterious that I thought we could use a little help from our inter-friends.
What does it mean oh internet???!?



































Poor little guy wore himself out trying to show it to me.
















Pretty good handwriting for a toddler, wouldn't you say?











Oh David- I know you can only speak in baby tongue, but sometimes you are sooo cryptic!
