when will zb say some words?

So, just realized that my son is 20 months and i am pretty sure that he says less words at 20 months than he did at 18. I am positive that he can take direction (when he wants to) but has very little to say besides "GAGA". He is an overall caveman. I need to take more video of him running because it is the cutest thing ever.
Matt has been out of town every week this month and only home late Friday night and leaving Early Monday mornings. Our weekends have felt crammed and rushed. We have an auction for work this week so in addition to having no hubby to help at home-I work with some really stressed out people. Matt gets home Friday night late and I work late Friday night and all day Saturday. I think I can. I think I can.
We are thinking about doing camping one night next week if it will warm up a little and we might even go to Dollywood.
I brought ZB to work today in his pajamas. I think he really likes it alot. He can be comfy eating breakfast and watching Mickey Mouse. He is a good boy. I am thinking about letting him go to Rivermont next year for 1 day a week. I had said I would I would not send him till he was 3 but I really think he would enjoy it and I could probably get alot done with him gone for a few hours.
Here is a pic of ZB doing the Hot Dog Dance in his PJS.
